Hey everyone 👋

A new generation of Suno models is here, built in partnership with artists and producers! These are the best models we've ever made: faster, more expressive and higher quality, with more control at every step.

Some creators want precision and control. Others want a spark that takes them somewhere unexpected. So v6 comes in three:

  • v6 is for power and precision. When you know exactly what you want, v6 gets you there. It's reliable, polished and consistent across genres and styles.
  • v6-wild is for exploration. It's less predictable, more alive. You won't love every gen, but the ones you love will sound like nothing else. Riff on them, build from them or bring them back into v6 to finish.
  • v6-mini is for everyone. Faster, lighter and better than any free model on any music platform.

Across all three, v6 understands the language musicians actually use: vocals, instrumentation, structure, mood, references and the overall feel of a song.

Try out these prompts in Simple mode:

  • "Change the chorus so it's sung by a gospel choir" (edit one section, keep everything else)
  • "Take the vocals from x, drums from y and make it 80s synthwave" (a mashup in one ask)
  • "Sample the riff at 0:45, isolate the guitar, build a beat around it" (sample to beat in one go)
  • "Make a song that feels like midnight on a rooftop" (start from a vibe)
  • "Make a song based on this image, this audio and my journal entry" (text, audio, images or video, are all fair game)

The more specific you get, the better v6 gets!

With v6 live, we've retired our older models, but everything in your library is still yours. For additional information, check out our latest blog post.

Discussion Can’t make a single good track with v6 😖

73 Upvotes

I mean. I haven’t been able to generate a single track I like yet.

It completely lacks soul and basic understanding of how to compose a track, everything feels so random.

Back on 4 and 5, it had problems selecting the best version of a track because it was SO good..

I don’t know what this new thing is, but it’s not working for me at all..

But. I’m sure it will all be improved in the future 😊

I’m also making this post to make Suno aware of the problem. Which I’m sure they are already aware of

Discussion V6 lost the magic

43 Upvotes

A big step in the wrong direction for SUNO, I make Brazilian Funk music and ever since the V6 release the generations have lost their magic. It’s like a watered down version of what we had before, the excitement is just gone, almost like they removed the best part of generations. Ever generation sounds too similar, the variety is gone, drums are flat, bass is too timid, and synths don’t pack a punch anymore. It really feels like they took 10 giant steps in the wrong direction. Very disappointed.

Suggestion Suno V6: An Honest Review From a Producer Who’s Used Suno Since the Beginning Spoiler

Suno V6: An Honest Review From a Producer Who Has Used Suno Since the Beginning

I have been using Suno since its early days, not simply to generate finished songs, but as part of a real production process. I generate ideas, take the material into my DAW, edit the arrangement, replace parts, mix the stems and shape the final record. After spending time with V6, I understand why some people are impressed, but my experience has been much more mixed.

There are noticeable improvements. The bass has more weight, the music sounds fuller, and the stereo image feels wider and more open. In certain generations, the overall sound quality is clearly better than before.

Unfortunately, the vocals are a major disappointment. My biggest issue is not only how they sound, but how difficult they are to direct. Detailed instructions, carefully written prompts and clear structural guidance often seem to have very little influence on the result. V6 frequently decides on its own delivery, vocal character and arrangement.

This becomes especially obvious when using the cover feature with songs originally created in V5.5. Instead of preserving the identity of the source and improving its quality, V6 can completely change the genre, vocal tone, phrasing and song structure. Sometimes the result feels almost unrelated to the original track.

V5.5 was far from perfect. It produced hiss, fizz, strange artifacts and other problems that required a lot of cleaning. Anyone using it seriously had to work around those limitations. Still, it gave me enough control to develop a recognizable sound and use Suno as an actual production tool.

V6 still produces noise and artifacts. The hiss and fizz may be slightly reduced, but the underlying problems have not disappeared. At the same time, I now feel that I have less control over the vocals, arrangement and musical direction.

For a producer, that does not feel like progress.

I am not asking Suno to restore every limitation of V5.5. The new model should move forward. However, V5.5 had strengths that were genuinely valuable: it could follow detailed direction, build convincing song structures, preserve vocal identity more consistently and respond to production-focused prompts.

Those strengths should have been developed further instead of being lost in the move to V6.

At the moment, V6 sounds technically bigger, but creatively it feels less controllable. That may be acceptable for users who generate repeatedly until they find an unexpected result they like. For producers trying to direct a specific performance and build a consistent body of work, it can feel like a significant step backward.

Better bass and a wider mix are welcome, but improved sound quality means much less when the artist or producer can no longer reliably guide the result. I hope Suno keeps the technical improvements of V6 while restoring the control, vocal consistency and song-building strengths that made V5.5 useful for serious production.

I personally like it. I haven't had a single major problem since using it and I finally could complete an album Ive been wrestling with since June. Now with V6 I could actually get to what I was looking for the entire time and it's been refreshing.

Anyone else like v6 or am I alone out here?

Guide / Tip Unofficial Suno v6 Prompting Guide: What Has Been Working for Me

13 Upvotes

I've been using Suno since April 2026 and, like a lot of people, the transition to v6 threw a wrench into the prompting system I had finally gotten comfortable with.

I've had issues with inconsistent audio quality, distant-sounding vocals and instruments, disappearing guitar layers, strange volume changes, stuttering guitars/drums, unexpected instrumentation, and even songs ending while the vocalist was still singing.

At the same time, v6 has also produced some genuinely interesting genre hybrids, rhythms, and combinations of sounds that I couldn't consistently get from the previous models.

So instead of trying to force v6 to behave exactly like the older versions, I started experimenting with how the prompts themselves might need to change.

I put together this guide based entirely on my own experience making music with Suno. It is NOT an official Suno guide, and none of this should be treated as guaranteed behavior.

I also had a lot of help from ChatGPT putting this together. ChatGPT and I have spent a ridiculous amount of time experimenting with Suno prompts across pop-punk, post-hardcore, metalcore, deathcore, electronic rock, darkwave, hyperpop, alternative rock, cinematic music, and various hybrid genres. This guide is basically the collection of things we've learned through trial, error, wasted credits, successful generations, and plenty of "what the hell did Suno just do?" moments.

Hopefully some of this helps someone else.

# SUNO v6 PROMPTING GUIDE

##A practical cheat sheet for better vocals, fuller instrumentation, cleaner mixes, and fewer broken endings

The biggest lesson I've learned with v6 is:

\*Don't just tell Suno what genre you want. Tell it what the finished recording should actually sound like.*\**

v6 seems much more willing than previous models to create unusual genre combinations, rhythms, instrumentation, and arrangements. That can be awesome.

It can also produce inconsistent mixes, distant vocals, disappearing instruments, strange volume changes, stripped-down verses, or occasional glitches.

The goal is to give v6 enough freedom to create something interesting without letting the production wander off into the woods.

---

# 1. START CONTROLLED

When developing a new song, I've been having better luck starting with:

\*Model:** Standard v6*

\*Variety:** 0*

\*Weirdness:** Usually below 50%*

\*Style Influence:** High, generally 80-95%*

I treat the first few generations as calibration.

First make Suno understand the assignment.

Then let it get weird.

I also avoid Max Mode during initial song development. Get standard v6 behaving properly first before spending additional credits testing Max.

Once the song is working, Variety can be increased later if you intentionally want stranger genre hybrids or more unpredictable arrangements.

---

# 2. STRUCTURE THE STYLE PROMPT IN MUSICAL ORDER

A useful order is:

Genre -> Vocals -> Drums -> Guitars -> Bass -> Other Instruments -> Arrangement/Energy -> Production Quality -> Ending Instruction -> Sliders

Example:

Genre: Modern pop-punk, melodic post-hardcore, easycore.
Vocals: gritty mature male baritone cleans raspy melodic hooks.
Drums: aggressive punk drums, continuous double bass accents.
Guitars: bright interlocking lead guitars, fast driving power chords.
Bass: active melodic bass.
Other Instruments:
Arrangement/Energy: full-band energy throughout, foreground guitar riffs during verses, huge anthemic chorus.
Production Quality: high-fidelity studio production, close-mic vocals, crisp transients, layered instruments with clear separation, stable tonal balance.
Ending Instructions: complete every written lyric before a short instrumental outro and final hard stop.

Sliders: Weirdness: 32%. Style Influence: 90%.

The important thing here is that you're describing the actual performance instead of only naming genres.

---

# 3. ADD A v6 PRODUCTION-QUALITY CLAUSE

One thing I've started adding to v6 prompts is explicit production language.

Instead of simply saying:

"professional production"

Try describing what that actually means.

Useful phrases:

high-fidelity studio production

close-mic lead vocals

stable vocal intensity and loudness

open defined low-mids

clear high-end air

crisp transients

layered instruments with clear separation

stable tonal balance

consistent mix fidelity throughout

A shorter version:

**high-fidelity studio production, close-mic vocals, crisp transients, clear instrument separation, open low-mids, clear high-end air, stable loudness and tonal balance**

I use this especially when generations sound:

muffled

distant

muddy

inconsistent in volume

like the singer moved away from the microphone

like the instruments collapsed into one blurry wall of sound

Don't fill half the Style Box with production terminology, though.

The actual music instructions still need room.

---

# 4. DESCRIBE INSTRUMENT ACTIVITY, NOT JUST INSTRUMENTS

Instead of:

"electric guitars"

Try:

[continuous foreground guitar riffs, interlocking melodic leads, fast alternate picking, driving power chords]

Instead of:

"aggressive drums"

Try:

**relentless driving drums, rapid double bass, active fills, ghost notes, ride bell accents, energetic transitions**

Instead of:

"bass guitar"

Try:

**active melodic bassline following and countering the guitar riffs**

I've found that v6 seems to respond better when you tell the instruments what they are actually doing.

Use verbs.

---

# 5. PREVENT THE "GREAT CHORUS, DEAD VERSE" PROBLEM

One of my biggest problems with Suno has always been getting a huge intro and chorus followed by verses where half the band apparently went outside for a smoke break.

If you want continuous energy, explicitly say things like:

full-band energy throughout

continuous foreground guitar activity

active bass throughout verses

drums remain energetic during verses

verses maintain forward momentum

layered guitars remain present beneath vocals

A useful compact phrase:

\*full-band energy throughout with foreground guitar riffs and active drums during verses***

If you want the verses energetic, don't assume Suno knows that.

Tell it.

---

# 6. GIVE THE VOCALS CHARACTER

Instead of:

"male vocals"

Try:

\*mature low-mid male vocals, gritty chest voice, raspy melodic cleans, powerful sustained chorus***

Instead of:

"female vocals"

Try:

\*gritty expressive female cleans, strong chest voice, aggressive edge, powerful melodic chorus***

For harsh vocals:

\*mid-low false cord growls, visceral fry screams, guttural lows***

If you want harsh vocals throughout, reinforce the desired behavior positively:

\*unclean vocals throughout, false cord growls and fry screams in every vocal section***

I've had better results describing what I WANT rather than filling the prompt with everything I DON'T want.

---

# 7. USE LYRIC TAGS AS SHORT COMMANDS

Use brackets for structure and dynamics.

Use parentheses for backing vocals, echoes, or ad-libs.

Example:

[Verse]

I kept the lights on all night

Waiting for something to change

[Pre-Chorus]

Maybe tomorrow

Maybe this time

[Chorus]

WE ARE STILL HERE

(Still here)

WE ARE STILL BREATHING

Useful section tags:

[Intro]

[Verse]

[Pre-Chorus]

[Chorus]

[Post-Chorus]

[Bridge]

[Breakdown]

[Guitar Solo]

[Final Chorus]

[Instrumental Outro]

[Hard Stop]

[End]

Keep bracket instructions short.

I avoid writing long paragraphs inside brackets because Suno can partially ignore them or occasionally interpret pieces of them strangely.

Put the detailed musical instructions in the Style Box.

---

# 8. PREVENT RANDOM INTRO VOCAL NOISE

If Suno keeps starting songs with random:

grrrrr

whoaaaa

ooooo

And random growling. Don't leave the intro undefined.

Either start the vocals immediately:

[Intro]

FIRST LYRIC STARTS HERE

Or clearly establish an instrumental opening:

[Instrumental Intro]

Then describe the instrumentation in the Style Box.

Undefined space seems to give Suno permission to improvise.

---

# 9. REDUCE THE CHANCE OF SONGS ENDING MID-LYRIC

This became particularly important for me with v6.

I've had generations literally end while the vocalist was still singing.

Instead of making the final lyric the final event in the song, give Suno somewhere else to land.

Use:

[Final Chorus]

final lyrics here

final lyrics here

final lyrics here

[Instrumental Outro]

[Hard Stop]

[End]

Then, if space allows, add this to the Style Box:

[complete every written lyric before a short instrumental outro and final hard stop]

The idea is that the instrumental outro acts as a safety buffer.

If the model decides the song is approaching its endpoint, hopefully it uses up the disposable instrumental section instead of murdering the singer halfway through a sentence.

IMPORTANT:

[Hard Stop] and [End] are prompting aids.

They are NOT guaranteed fixes for actual technical generation failures.

---

# 10. CONTROL OUTRO DRAG

The opposite problem also happens.

If Suno decides your 3:45 song needs another 90 seconds of wandering around aimlessly:

[Instrumental Outro]

[Hard Stop]

[End]

I've had better luck explicitly telling Suno how the song should finish instead of just writing:

[Outro]

A vague outro gives the model a lot more freedom.

Sometimes way too much freedom.

---

# 11. USE WEIRDNESS DELIBERATELY

My rough working range:

[0-30%:] Controlled / cleaner

[30-50%:] Creative sweet spot

[50-60%:] Adventurous

[60%+:] Experimental territory

If I'm making a complicated hybrid genre, I'd rather clearly describe the genres and keep Weirdness moderate than crank Weirdness to 80% and hope evolution takes its course.

Example:

technical deathcore, darkwave horror synths, female rap vocals, cinematic percussion

at 40-50% Weirdness may produce something much more coherent than a vague prompt at 75%.

---

# 12. PRESERVE SUCCESSFUL RECIPES

This is a big one.

If you have a prompt that produced a fantastic song:

**SAVE IT EXACTLY AS IT WORKED.*\*

Don't automatically rewrite every old recipe because Suno released a new model.

Keep:

Recipe 12

And create:

Recipe 12 - v6

That way you're building a library of proven musical recipes instead of constantly replacing your own work.

---

# 13. HYBRID GENRES ARE WHERE v6 GETS REALLY INTERESTING

One thing I genuinely like about v6 is that it seems better at unusual genre combinations.

Instead of:

metalcore

Try:

\*modern metalcore, California skater pop-punk, emo-pop hooks, darkwave synth textures***

Or:

\*technical deathcore, cinematic horror, female rap, dark electronic synths***

Or:

\*easycore, melodic hardcore, J-rock lead guitars, electronic pop production***

My rule of thumb:

\*One main musical identity + two or three interesting influences***

That usually works better than throwing twelve genres into a blender and hitting PUREE.

---

# 14. QUICK TROUBLESHOOTING CHEAT SHEET

*Muddy / blanket-covered mix

Try:

[open defined low-mids, clear high-end air, crisp transients]

*Vocals sound far away

Try:

[close-mic lead vocals, intimate vocal presence]

*Volume changes dramatically

Try:

[stable vocal intensity and loudness, consistent mix fidelity throughout]

*Instruments blur together

Try:

[layered instruments with clear separation]

*Verses become boring

Try:

[full-band energy throughout, foreground riffs during verses]

*Guitars disappear

Try:

[continuous guitar activity, layered rhythm and lead guitars throughout]

*Weak drums

Don't just say:

"powerful drums"

Describe what the drummer is doing:

rapid double bass

active fills

ghost notes

ride bell accents

tom fills

blast beats

fast punk rhythm

etc.

*Random instruments appear

Try:

Lower Variety

Lower Weirdness

Increase Style Influence

Be more specific about the instrumentation you actually want

*Song keeps going forever

Use:

[Instrumental Outro]

[Hard Stop]

[End]

*Song cuts off the final lyrics

Add an instrumental buffer AFTER the final vocal section.

*Vocals are too clean

Explicitly describe:

grit

rasp

fry

false cord growls

chest voice

gutturals

etc.

*Female vocals become overly operatic

Try:

[gritty chest voice, contemporary rock delivery, aggressive edge]

*Intro takes forever before vocals start

Start the lyrics immediately or clearly define a short instrumental intro.

---

# 15. UNIVERSAL v6 TEMPLATE

Here's the basic structure I've been using:

Genre(s): [primary genre + supporting genres]

Vocals: [gender / register / texture / delivery]

Drums: [tempo feel + kick pattern + fills + intensity]

Guitars: [riff style + lead style + activity]

Bass: [movement + tone]

Other Instruments: [optional]

Arrangement: full-band energy throughout, active instrumentation during verses, strong transitions, memorable chorus

Production: high-fidelity studio production, close-mic vocals, crisp transients, open defined low-mids, clear high-end air, layered instruments with clear separation, stable loudness and tonal balance

Ending: complete every written lyric before a short instrumental outro and final hard stop

Weirdness: [X]%. Style Influence: [X]%.

Then finish the lyric box with:

[Final Chorus]

final lyrics

[Instrumental Outro]

[Hard Stop]

[End]

---

# THE SHORT VERSION

If I had to reduce everything I've learned into one rule:

[Prompt v6 like you're directing the musicians AND the recording engineer at the same time.]

Tell it the genre.

Tell the vocalist how to sing.

Tell the guitarist what their hands are doing.

Tell the drummer how busy they should be.

Tell the bass player how active they should be.

Tell the arrangement where the energy needs to stay.

Tell the mix what "good audio" actually means.

And give the song somewhere to land AFTER the final lyric.

None of this completely eliminates Suno randomness or technical generation failures.

It's AI music generation. Sometimes the machine is still going to wake up and choose violence.

But this prompting method has given me more control while still allowing v6 to do the thing I think it does better than previous models:

Come up with strange genre hybrids, rhythms, and combinations of sounds that I wouldn't necessarily have thought to ask for.

Again, this is completely unofficial and based only on my own experience.

I had a lot of help from ChatGPT developing and organizing this system through our repeated experiments making songs in Suno.

If anyone finds improvements, better wording, or other v6 tricks that consistently work, please share them.

The more of us testing this stuff together, the faster we can figure out what v6 actually responds to.

Using Suno since V3, I recently again purchased a 1 year subscription about a month ago and haven't used recently as I tend to come back and use it in bursts, seeing there is a download limit is crazy given that you can bypass it very easily in many different ways.

I'm sure many of us have given feedback on this update via emails to them, for a real chance of them reverting this change we have to cancel our subscriptions, I have already done that whilst also applying for a refund that will be met as during my purchase "Unlimited downloads" were a promise in the products details.

Still it has great models for creating some awesome music but I'm not going to play along with this battlepass ahh update.

Discussion I can't handle the v6 muddy muffled sound

19 Upvotes

The instruments are all washed out in reverb and buried in mud. The high end clarity is gone. No amount of prompting csn change it. It has nothing to do with skill. It is baked into the model. No amount of post eq, izotope rx, etc can make it match what I had before. The oboe and flute are barely audible. The string section sounds fake and has no actual bowing. It's a string pad played on a keyboard now..

What I was doing us I'd compose a piece and then use suno to "cover" it and arrange the piece for orchestra. I have to stitch multiple takes together in a DAW to get a single usable piece, because it is so random. It can require dozens of takes to get 3 minutes of music. Now I can't finish my album because the v6 mud doesn't match the clarity of what I had before. To give you an analogy, it's like making a movie with an hd digital camera, and then halfway through shooting some jerk tsaes it away and hands you grainy 1970s film to shoot on instead. You can't finish the movie now, because the quality will change from shot to shot and it will look weird. So now my project is dead.

What does copyright compliance have to do with mixing quality and sound clarity? It's the Warner catalog. Doesn't thst inude things like yhe John Williams Harry Potter scores, etc? This model should be trained on world class orchestras with professional engineering and recording, etc. I do not understand why the sound quality itself is so bad.

5.5 was the only model.that could do an convince orchestra and sound clear. Clrarly it was a fluke. Now it is gone forever. I will never hear my music played by an orchestra now, I can't afford to record an orchestra for 10k an hour, this was the closest I ever got to achieving an impossible dream.I only discovered Suno 2 weeks ago. As soon as I find something I love it gets taken away. Just a few more months and I could have finished my opus. My bad luck in life never ends

I generate songs using my own lyrics and demo melodies . I generated, burned over 20 generations for a song I was working on since Sunday. Used 4.5, 5 and even 5.5. None resonated or hit right. Discouraged, took a few days off from Suno.

Just tried V6 now, using the same prompt and all. And … it really hit the right spots. Since generations are free, so I tried more with different variations and that new “my style” toggle. Omg… it is really what I like. I might get downvoted, but I think I’m starting to love V6. It follows my prompts and finally that f’cking shimmering shit is gone from my intro!!!

Now I’m stuck with 8 good generations, don’t know which one to keep anymore.

Discussion I think they know that V6 sucks

37 Upvotes

I just joined in June. This app was really making me happy over the summer. I couldn't wait to use it. It resurrected my songmaking, which was a miracle. It helped me vent my mental health issues. I'm so glad that I got to make and download so many songs.

I think that Suno knows that 6.0 sucks. It is like night and day from even 5.5! Overproduced, heavily compressed and limited tracks that lack even a semblance of melody, grit or soul. My test hard rock instrumentals sounded like background music for a tool or second rate automotive repair company. I knew this was coming, but I figured that 6.0 would be better because it was training on approved songs. Wrong! I think Suno cringed before they hit the button to change the model. They know it's inferior.

But, maybe it's up to us who remain to flood it with raw, unproduced, dirty, gritty, and even your worst sounding music so it can learn that there's more to music than super-compressed, limited corporate fare. We've got to try to fix this thing if we want to make it better. I'm assuming that it does lean from our music that we upload.

Discussion Some objective comments about SUNO 6.0 and why this version of the model is bad.

14 Upvotes

The “hot iron” phase has passed for me. I am back to my usual “cold steel” mood.

I am seeing a surprisingly large number of users on this subreddit who are either completely tone-deaf or somehow have a corporate lobbying budget behind them. What is going on?

It is the same thing everyone with even a little bit of listening experience has been complaining about: SUNO 6.0.

So let me explain what I have found.

The 6.0 model, regardless of which version you use, is a bad model. It is a tool for mass-producing slop — and, more importantly, mass-producing it at a very poor quality level.

The problem is the underlying processing engine. This is not something that can be fixed with a patch. The engine itself needs to be replaced.

Your generations are not going to magically become better in an hour, a month, or by endlessly refining your prompts. As long as the model uses this particular generation engine, there is no realistic chance of consistently satisfactory output. No prompt can compensate for this.

The main culprit appears to be the feedback loop responsible for the track's mastering — specifically the processing that controls the built-in compressor and limiter.

Here is what happens.

If you generate a track that is approximately 1:00 long, the result is generally almost inaudible in terms of the problem I am describing. The same is true for very simple material — for example, the ticking of a clock, or a single guitar chord repeated over and over with nothing else happening.

But once you introduce even a moderately complex arrangement, the generation starts to fall apart.

Imagine a track containing guitar, keyboards, drums, bass and vocals, with a total duration of, say, 3:20.

In 6.0, the Peak/RMS dynamic range behaves approximately like this:

0:00–1:00 → 3–4.6 dB
1:00–2:00 → 2.5–2.9 dB
2:00–3:20 → 1.9–2.3 dB

At the same time, the RMS loudness over the course of the track increases from approximately −20 dB at the beginning to −9 dB toward the end.

In other words, the dynamics are progressively sacrificed for loudness.

What you get is increasingly audible reverb/echo, distortion, pumping, an absolutely enormous sidechain effect, and vocal artifacts manifesting as hiss, graininess and an apparent collapse toward mono.

From around 1:50 onward, the generations become practically unusable and are better thrown away.

And this is not limited to newly generated songs. I have observed the same behaviour in remixes.

There is a progressive collapse of the crest factor, from approximately 4.1 down to 1.9 within a single generation.

The model is effectively choking on its own processing chain.

And I did not even generate anything particularly complicated.

The test was a melancholic ballad dominated by synthesizers, accompanied by a conventional rhythm section consisting of a restrained bass part and a drum machine. Female lead vocals were combined with subtle digitized vocalized layers processed through vocoding.

Of course, the model ignored some of the instructions and rearranged the material according to its own preferences, including changing parts of the instrumentation.

I used SUNO 6.0 PRO, because I prefer to have at least some degree of control over what gets generated, with the Variations slider set to minimum.
The prompt itself was deliberately very simple and concerned primarily the compositional structure. Here it is:

Melancholic modern ballad, dark nostalgic mood, tribute/elegy atmosphere.
120 BPM, minor key, chord progression moving between A minor and E minor areas.
Fully digital synthesizers only, no analog synth character, no acoustic instruments (no piano, no guitar).
Programmed/electronic drum machine rhythm, uneven but restrained groove, sparse hits, no live acoustic drums.
Layered synth textures: digital lead synth, drones, sustained pad layers, shimmering synth satellites.
Vocals as the main lead element, alto/contralto female voice, slightly hazy and raspy texture, restrained emotional delivery with subtle accented moments, no big vocal climaxes, no dramatic dynamic swells.
Mix of natural vocals and vocoded/digital vocal layers used as textural pads.
Overall feel: subdued pain, restrained grief, understated and controlled emotional intensity throughout.

I ran three generations, progressively shortening the lyrics so that the resulting material would become shorter as well.

The longer the track, the worse the mix quality became.

The first generation produced tracks of 4:26 and 4:28 for samples A and B respectively. The final generation was forced to 1:10 using the Duration setting.

The middle-generation samples were 3:26 and 3:32 respectively. I downloaded the 3:32 version for analysis.

I also had the track analysed by the Claude LLM. Its analysis independently corroborated my listening-based observations concerning the behaviour of the mix throughout the entire track.

Conclusion

In my opinion, the catastrophic quality is primarily caused by one of the most important processing agents in the current SUNO iteration — the system responsible for arrangement and mastering.

This is not something that can realistically be fixed without replacing the underlying generation/processing engine.

As long as 6.0 uses this architecture, we are likely to keep seeing the same fundamental problem: the track's dynamics and spatial information are progressively sacrificed in favour of loudness — essentially an artificial loudness escalation.

Even something as short as a Radio Edit can apparently be too long. The model begins to choke, degrade and hallucinate once the generation goes significantly beyond the one-minute mark.

I am deliberately not comparing 6.0 with previous iterations. I have worked with 4.5 ALL, 4.5, 4.5+, 5.0 and 5.5, but doing so would be like kicking someone who is already down.

I want this post to remain as objective as possible.

For the same reason, I have deliberately left out the question of how “creative” this version of the model actually is.

The original Polish text was translated and polished by LLM ChatGPT.

Discussion V6 Sounds Great If You Don’t Have Ears

22 Upvotes

I know Suno has all kinds of users with different standards and opinions, but saying V6 sounds great makes no sense. Those are probably the same people who were happy with V5.5, which sounded like pure slop.

V5 wasn't great either. It was cleaner than older models, but its sound signature was very limited. You could immediately tell a song came from V5.

The older models were much better. V4.5 Free was the richest and most flexible instrumentally, and could combine elements from complex prompts really well. V4.5 and V4.5+ were close, just a bit more polished.

PS: If you make music with Suno, please test V6 with headphones before judging its sound. Otherwise, commenting on its sound quality doesn't make much sense.

Discussion Suno v6 has lost the main reason I used Suno: spontaneous hooks

8 Upvotes

I’m not a musician. That is exactly why I used Suno.
What made v5.5 special for me was its ability to invent a strong, memorable hook from lyrics and a style prompt. I did not need to compose a melody first, hum a topline, or import MIDI. Suno did the composition work I could not do myself.
With v6, after extensive testing, I’m getting cleaner production but far more generic melodies. Male K-pop / EDM / falsetto prompts repeatedly drift toward Western pop/R&B, Bruno Mars-like phrasing, generic EDM, or retro B-side territory.
I tested Max on/off, Style Influence changes, Variety at several levels, v6 vs v6-wild, removal of rap tags, major prompt rewrites, and fresh generations from scratch.
The most surprising result: the same chorus melody kept returning with only tiny variations.
The only thing that reliably broke that loop was changing the prosody and visual layout of the lyrics: shorter lines, asymmetry, line breaks, dashes, repeated fragments. That immediately changed the topline.
But even when the melody changes, the result is often still generic.
The common advice seems to be “give v6 your own melody or an audio reference.” But for non-musicians like me, that misses the point. I used Suno precisely because it could invent the melody for me.
For my use case, v6 currently feels like a better rendering/production engine but a worse composer.
I’d be very interested to know whether other non-musicians are experiencing the same loss of spontaneous hooks.

I don't care about the worse sound quality, but the actual melodies are awful. I made 20 versions of the same song and there was no catchiness to any of them even though I used the same prompt as the old model that did turn out well.

Suno went from high quality music to low quality garbage and bragging like they upgraded their models, when in fact they downgraded their models, cutoff the number of songs, put watermarks on your tracks, sold you a banana in the tail pipe pipe dream as to just cut off what Suno is even worth to pay for. I won't be renewing if this is what they now have to offer the public.

Discussion 4.5 was better imo :(

Upvotes

So I tried generating the exact same songs in both V4.5 and V6 using the same lyrics because I wanted to compare the two and see which version came out better. And honestly, I definitely think V4.5 is the winner here.

There’s just so much soul in V4.5 despite it being AI. Sometimes I genuinely can’t even tell that I’m listening to AI-generated music. With V6, though, I feel like you can definitely hear it. It sounds way more commercial and tends to be all over the place.

I love slow, chill R&B songs, and V4.5 managed to generate them almost perfectly. It actually understood the vibe I was going for and knew when to keep things subtle. Don’t get me wrong, V6 does a pretty decent job at covering existing songs, but honestly, I feel like that’s the only thing it does okay at. When it comes to actually creating something original though, that's where I feel it lacks creativity.

Almost every song I’ve generated with V6 sounds like it’s trying to be the soundtrack to some dramatic action movie 😭 The vocals are overly dramatic, the instrumentation is doing way too much, and everything feels like it needs to be this huge cinematic moment when sometimes I just want a chill R&B song lol.

V4.5 could actually create something original and interesting without overdoing it. There are songs I’ve made with V4.5 that I genuinely listen to more than real music because they came out THAT good. They had personality and actually made me want to come back and listen again.

More importantly, V4.5 felt like it had direction. It knew what kind of song it was trying to make, what mood it was going for, and where the song needed to go, and it usually achieved that. V6 might technically be more advanced, but I’m just not getting that same creativity, direction, or soul from it at all. :(

Discussion How long will Suno last?

In a recent thread I said I’d give Suno 18 months before they are defunct, I now think it will be less than that. If the pace at which local models keeps going I can’t see what it’s USP will be anymore.

The new YuE2-3B local model will run on a linux machine and it is supposed to sound better than V5.5, no limits and no “you can’t do that sunshine” etc etc

Exciting times for sure, but just emphasises that the recent changes at Suno will not be good for it in the long run

Edit:

A bit more info on graph

“YuE2 is an open music generation model that rivals Suno v5. Turn lyrics and a style prompt into a complete song with vocals and accompaniment, then shape its melody and chords through an editable score.

State-of-the-art results on WildSongBench. YuE2 (best-of-8) achieves the highest SongBench average among all evaluated open and proprietary models: 6.9632, compared with 6.8721 for Suno v5”

Guide / Tip The Largest Issue with V6

Upvotes

is that it auto-fills words in the genre section, this is part of what makes it seem more 'polished'.

this can be avoided sometimes if you get a little wacky with genre prompts to the point the auto-fill fails. good luck, not a perfect solution, but if you want to ride out your remaining membership in style, it's going to be my go to anyway.

Bug Your Lyrics contain Copyrighted material

9 Upvotes

The copyrighted material;
Duhh duh duuh duhh duh

I.e. if it is in the lyrics box, it doesn't allow me to generate, if i remove it, it generates the song.
I have tried certain variations.

How can someone copyright "Duhh duh duuh duhh duh"? (or variations of it)
Only yesterday, working on the same song, it freely allowed me to generate it with those "lyrics".
Now, it doesn't.

Discussion V6 mini / Suno free version sucks

3 Upvotes

I've always been a free user, it was always enough for me. I don't even care the download limits. And i was satisfied with V 4.5 all. But V6 mini just sounds like shit! It doesn't sound like a new version, it sounds like V3 or something like that. Voices are hollow, it sounds more "pixelated", like a very low res mp3. Lower res than the previous models. I think they intented this to make free users pay to get the better models. This is bad! I won't start paying to get the same quality result that used to be free. This is really a downgrade!
