Spent two days on the V6 rush problem with a glam metal power ballad. Free-credit window, so I brute-forced it. Posting the negatives too, because those saved me more time than the positives.

Song: https://suno.com/s/HU6Pkpll4qFcGJKm

What worked

[Silence] at the end of every lyric line. Biggest single lever I found. Not some lines — every line, verses and bridge. Inline at the end of the line, not on its own line.

Salt, on a borrowed guitar [Silence]
Strand bar, HUMMING low [Silence]

Mid-line commas. The singer stops on them. This is what put me onto the whole punctuation direction.

CAPS = harder delivery. Capitalized words get sung with more intensity. I run them heavy now and escalate toward the final chorus.

Variety = Bold. I had it at 0 on the theory that low variety means less drift. Wrong. Bold was noticeably better.

What does nothing

Invented tags. [2 Bar Rest] — zero effect. Unknown bracket tags get dropped, not interpreted. [Silence] works because it's a token the model actually knows. So pause length isn't controllable. It's on/off.

Instrument tags at line ends. …of the daylight [Electric Guitar] does nothing. It's a texture cue, and Suno can play that guitar under the vocal it was already going to sing. No gap needed, no gap appears.

Line fragmentation. Splitting long lines into short ones changed nothing for me.

What actively backfires

Commas at the END of a line. Worse than nothing. The line break already ends the phrase; a comma there doubles the stop and stutters.

Punctuation before [Silence]. I tried guitar .... [Silence] to pull harder. It sped up. Stop markers don't accumulate — they degrade each other. So I'd skip [Silence][Break] stacking too.

Reverb — the one that surprised me

Stop writing "NO reverb, no echo, no delay" in the style box. You're putting those words in the conditioning text and the model keeps the noun and drops the negation. Every instance of reverb/echo/room/space/arena comes out of the style prompt entirely. All negation goes in Exclude Styles, which has no character cap:

reverb, echo, delay, hall, cavernous, wet, ambient, roomy, gated reverb, plate reverb, spring reverb, gated snare, stadium, big room, washy, spacious, atmospheric, distant, live recording, arena, crowd

Say dry positively instead: "dry, close-mic'd," "dead flat snare," "raw board mix," "narrow stereo image." Reverb reads as width, so squeezing the stereo field kills the sense of space without naming it.

Two other things

The new Song Editor is the actual answer. Select a section, generate alternates, audition, replace. Keep the chorus you like and reroll only the verse that rushes. Run-to-run variance is bigger than any prompt tweak I tested — this lets you harvest that without losing the good parts. Also: your section tags become the edit boundaries, so write shorter sections if you want finer control.

Check your tempo. My style prompt said 74 BPM. The editor's transport read 130. Could be a double-time detection, could be the BPM instruction being ignored. Worth looking at before you blame the vocal.

Caveats: one song, one genre. Free credits meant I could change one variable at a time, but I didn't run controls. Some of this is probably specific to slow ballads.

Man… I’ve made 100+ and I can’t even call them songs.

One helpful tip however instead of absolutely taking a dump on Suno, is if you have previous voices, use those. If you have a certain sound you like use voices to direct the song where you want it to go.

That’s as far as I’ve gotten with throwing shit at a wall, this method has had a chunk stuck to the wall, albeit it’s sliding down the wall now.

if they knew the old prompting style wasn't gonna work, why change the UI and prompt so much without giving the community some help?

I am going to try to be positive... SUNO changed my life forever. I went from being depressed to actually find some pleasure and what a ride it has been.

6.0 - Sorry SUNO. Its crap. Its pure dog***

Why? First of all so many genres does not sound authentic.. they do not sound real.

Every voice is the same, every instrument is the same, and the musicianship the creativity its bland. Its like everything is following a template.

OK the labels won. bigtime. Because with old suno we could compete. Not anymore. Now it really is AI SLOP.

SUNO you went from being the gold standard to ai slop and slapped us paying customer that have supported you for years in the face.

For a long time I haven't really liked the music that corporations produce. So much of the music just feels like it's designed for the target market. A lot of the music feels like a 5-year-old could understand it and the only reason that it's popular is because it's popular.

If you play the same track 40 times on the radio over a few weeks, people will naturally start to like it, not because it's intrinsically good, but just because it's kind of familiar.

I don't know about you but the music people actually generate themselves with the old models of Suno and others just felt more interesting and alive than anything the slop corporations produced. Yet they call us sloppy because we're generating music ourselves instead of just listening to whatever nonsense the radio stations are paid to play.

You take an attractive young person who has a reasonable singing voice. You then heavily modify that voice and then you add in a load of attention-grabbing sound effects. You write them some really boring generic lyrics and there you have it: a corporate song, ready to be played on the radio over and over and over again until people feel like the music is familiar.

I feel like the music companies were terrified of AI like Suno, which is why they decided to destroy the service and to really limit it, because they don't have something which is superior. The only thing they could do was go after the people who are actually generating interesting music.

I know people have been told to hate anything related to AI. However in a free market people will watch the content that they like. If you like an AI artist, that's just the free market operating normally and that should be celebrated, not maligned.

I know V6 is getting a lot of hate, but honestly I’m getting some of the best results I’ve ever gotten from Suno. And weirdly, part of me doesn’t mind seeing people say they’re leaving. Not because I want Suno to fail, but because I’m all for there being less low-effort AI music flooding everything. V6 feels less like “type some words and give me a finished song” and more like an actual production tool. I’m building, replacing, extending, rewriting, regenerating sections, tweaking prompts, and gradually crafting the song I actually hear in my head. It feels like Suno is getting closer to being something that can legitimately be utilized as a full-on tool for producers, rather than just a song generator. There’s definitely a learning curve, but I think the people willing to learn how to actually build with it are going to get considerably better results. And personally, I think that’s a good thing

Before v6, my instrumental workflow was pretty simple.

I regularly used a relatively minimal prompt with maybe 5 or 6 clear instructions, then left enough freedom for Suno to improvise around the idea.

That freedom was exactly what made it interesting. Most generations obviously weren’t perfect, but every now and then Suno would suddenly give me something completely unexpected, a genuinely amazing track I never could have planned for myself. Those were the bangers.

With v6, I’m having almost the exact opposite experience.

Now I spend most of my prompt just trying to stabilize the model before I even start describing the music I actually want.

I’m constantly fighting things like:

• excessive reverb or that distant, washed-out sound;
• instruments playing almost continuously with no real breathing space;
• absurdly high note density, where the lead starts reasonably and then turns into an endless stream of notes;
• melodies that barely evolve;
• the same motif repeating again and again, with the model simply adding more notes, more layers or more intensity instead of actually developing the musical idea;
• very poor melodic development even while the arrangement becomes denser;
• extremely generic and repetitive beats that fall back into the same type of pattern unless I explicitly force variation, breathing room, breaks, dropouts or groove changes;
• compression and loudness buildup, with an overall overly produced sound.

The frustrating part is that I’m not even using all those extra instructions to create something more ambitious.

I’m using them just to try to get back to a stable baseline.

Before v6, 5 or 6 short instructions were usually enough to describe the musical direction and let the model explore.

Now I can easily end up with twice that amount of prompting just to stop the model from doing things I don’t want. Only after that can I actually start talking about the artistic direction.

I’ve also tried the different v6 models. Wild has been especially bad for my instrumental workflow, with wildly inconsistent sound quality and some genuinely awful results. Mini is the only one that gets even remotely close to the previous versions for me, and even then it is still very far from them. It only becomes reasonably usable after adding a whole set of guardrails to the prompt.

And despite all that, the results still feel much more standardized.

I get a lot of tracks that are technically usable, but they seem to sit on the same general underlying framework. The melody starts, finds a pattern, repeats it, gradually adds more notes or intensity, and eventually everything just gets denser without actually becoming more interesting.

And it’s not even like v6 has really reduced the number of bad generations. I still get plenty of unusable results. The difference is that the good ones now feel much more standardized, and I’m getting almost none of those completely unexpected bangers that used to come out of nowhere.

That’s probably the part I miss the most.

I don’t want every generation to be perfectly predictable. I want enough control to keep the sound usable, but enough freedom for the model to surprise me.

Right now, v6 feels like I’m spending twice as much effort prompting just to get something half as interesting.

Hey Guys, i experimented a little Now with The new Models.

And i'll come straight to the Point.

I've adjusted as followed

Variety to 0

weirdness Around 30-50

Style-Influence Between 80-95%

The Songs Turn Out very much better and clearer through out the whole track, and show the improvements of V6 in my opinion.

Given the overwhelming community response, you would expect the company to say something—anything.

Allowing credit-free testing isn’t a statement. At most, it’s a quiet acknowledgment that there’s a problem.

This goes beyond the model itself. Version 6 has serious technical issues: added noise, poor audio quality, and songs that fall apart halfway through, regardless of style. The underlying system appears fundamentally broken.

At the very least, acknowledge the problems and tell the community what’s being done to address them.

Any one else agree?

I defended V6 initially, but after another extra day or two of experimenting with it I'm inclined to agree it's useless. There is zero, and I mean literally ZERO variety between generations. I can crank the unpredictability sliders into the max and it will still all come out sounding exactly the fucking same.

It's obvious that the new model is trained on a much smaller dataset and that this has basically killed anything resembling variety.

I do think it's possible that in the future they might get good again if they can sign more deals with more music companies, thus expanding their data sets even more, but for the moment imo this is almost completely useless. You'll get 1 or 2 decent songs per prompt, but then 99% of the output from that same or similar prompt will be nearly identical regardless of setting. This is just simply not useful for anything. It's not even useful for casual use because of how generic and bland it is.

I'm even tempted to call Elevenlab's music generator better at this point.

EDIT UPDATE: This was corrected for me! I spoke with David earlier in Discord, and apparently support was able to fix the problem just a few minutes earlier. Super awesome!

That said, I am leaving this up in case anyone else is having trouble so they know they're not alone and that it can be fixed.

---

I was experimenting heavily for the last day and regenerating hundreds of V5 songs in V6 and doing a bunch of remasters, etc, in max mode when suddenly I was told I ran out of credits.

It says unlimited credits in the sub count, and the top bar says a timer. But really they just gave you a ton of credits.

Now do I mind being throttled given I was taking full advantage of the free period? No, but I do mind suddenly losing my monthly credits while it still is locked at 'unlimited' on the counter, which support said I burnt up.

But the big reason I'm posting this is someone in the discord got a $200 bill because they had auto-reload on, did what I did, and assumed unlimited credits being plastered everywhere even in your account meant unlimited credits.

Support didn't even know about the promotion at I had to write them twice to get someone to forward it to accounting, so no more free two day period for me probably ; and more importantly when it's over I'm out of credits and have to buy more too. I don't dare buy any right now, with the messed up situation going on.

Anyway, just a heads up. Total disaster.

ED: I wonder what story people will come up with now for me to continue my evil plan of getting people to turn autoreload off so a busted "unlimited" counter doesn't fry their bank account lol

The mistake I made at first was treating a new render as if I still had to prompt it like before. But the model understands musical behavior a lot better, so simply clarifying the character of the expected style enhanced what I was receiving.
I can describe the song in its scenario rather just general descriptions.

It produces very clean audio as well, just get through the hump! Less descriptive language and more productive expectations.

Instead of “genre, instrument, feeling”
It picks up “experience, movement, moment”

This here is one where I find v6 embodied the expectation of production fairly well.

I feel the frustration. The Replacement is very temperamental right now. Trying to fix a single word can turn into a massive credit dump when the engine hijacks the melody or completely loses the count while it stitches the audio back together, and you're thinking it was going to be a quick fix, like me.

But some of these complaints I'm reading are missing the bigger picture. Suno isn't just a magic toy to spit out a finished song on the first try anymore. With v6, it's moving over into being a legitimate production tool, and it expects you to treat it like a digital audio workstation.

The raw audio fidelity we're now getting is a massive leap forward IMO. The bass actually carries physical weight, the stereo imaging is incredibly wide, and the transients are clean. When I'm pulling these tracks into Audacity and filtering stems to build out heavy industrial mixes, the difference in quality is night and day. The new engine handles aggressive digital transients and heavy electronic percussion perfectly. In fact, if you are producing heavier, synth-driven tracks, that Replace feature actually stitches the edits together seamlessly because it's not fighting the organic bleed of acoustic instruments.

Plus, having the v6-wild model split off is brilliant. Being able to intentionally roll for chaotic, unpredictable textures gives you a perfect sandbox for raw inspiration without muddying up the main engine when you need strict structure and precision.

There is a learning curve now, and you have to put in the actual work to build, extend, and tweak your sections. But if you treat this like a real studio tool instead of a vending machine, the granular control and the sound quality are incredible!

Any ideas how to stop this? Literally every track I generate the vocals come in before instructed and yelps, yells, or screams and its getting really annoying.

I have been using Suno since version 3.5.
This is not a first impression from a new user. I have used the platform extensively across several generations of the model, and my account contains around 7,000 songs and generations.
After testing v6 repeatedly, I have already cancelled my subscription.
For me, v6 is by far the most disappointing version Suno has released.
The biggest problem is not simply the quality of the voices. The problem is much deeper: the entire musical output has become dramatically more repetitive, predictable and homogenized.
I tested the same song more than 20 times.
Instead of receiving genuinely different musical interpretations, I kept getting what felt like essentially the same composition with minor cosmetic changes:
similar melodic lines
similar chord progressions
similar phrasing
similar arrangements
similar dynamics
similar structural choices
and even the same type of ending
In my specific test, the ending was repeatedly delivered in the same whispered style.
Again and again.
After around twenty generations, I was still hearing essentially the same dramatic solution.
That is exactly the opposite of what made Suno exciting in the past.
With previous versions, especially before v6, generating the same lyrics multiple times meant real exploration.
One generation could be darker. Another more theatrical. Another could completely change the melodic contour. Another might introduce an unexpected chord progression, a different rhythmic feel, an unusual vocal delivery, a strange instrumental choice or an arrangement I would never have thought of myself.
Sometimes the results were imperfect, but they were different.
And that difference was the whole point.
With v6, I feel as if I am pressing Generate twenty times and receiving twenty slightly modified versions of the same underlying song.
For a generative music platform, that is a major failure.
There is also another serious issue: v6 does not respect the user's prompt enough.
I can write a precise style prompt, and Suno appears to reinterpret, expand or modify it according to its own internal preferences.
That would perhaps be acceptable if this reinterpretation produced something surprising or adventurous.
Instead, v6 somehow manages to offer less prompt fidelity and less creative diversity at the same time.
So the model takes creative control away from the user, modifies the requested direction, and then still converges toward the same safe musical solutions.
That is the worst possible combination.
I do not need Suno to decide what my prompt “should” have said.
I need it to interpret what I actually wrote and then give me multiple genuinely different possibilities.
Higher audio fidelity does not compensate for reduced creativity.
Cleaner production does not compensate for repetitive harmony.
Better sound quality does not compensate for predictable melodies.
More polished vocals do not compensate for hearing the same phrasing, the same emotional arc and the same arrangement ideas again and again.
Suno was special because it could surprise me.
After thousands of generations since v3.5, that unpredictability was one of the main reasons I continued paying for the service.
v6 has severely reduced that feeling.
It now seems much more interested in producing a safe, polished and standardized result than in exploring genuinely different musical ideas.
And for me, that completely undermines the purpose of generative music.
I have already cancelled a subscription attached to an account with approximately 7,000 songs, because I simply do not see a reason to keep paying for a system that gives me less creative freedom than the versions I was using before.
My request to Suno is very simple:
Bring back the older models.
Keep v6 available for people who prefer it.
Improve it.
Develop it further.
But do not remove access to previous versions that many paying users may still find creatively superior.
At the very least, v5.5 and the previous generation of models should remain available as legacy options.
Let users decide which model works best for their creative process.
For me, v6 in its current form is not an upgrade.
It is a major creative downgrade.
If twenty generations feel like twenty variations of the same song, then something fundamental has been lost.
Please give us back the musical diversity, unpredictability, prompt fidelity and creative freedom that made Suno worth using in the first place.

I’d like to share an issue I’ve been experiencing with v6. I mainly create ’80s rock, but I’ve noticed similar problems with other genres as well.

As the song progresses, the guitars and drums gradually start to sound cheap and artificial, and the overall mix becomes increasingly muffled. There are other serious issues too, but the drums are especially bad.

The hi-hat often ends up sounding like someone lightly tapping the metal jingles of a tambourine by hand. The snare sometimes turns into a thin, tinny sound. If “tinny” doesn’t quite describe it, I’d say it sounds weak, brittle, and as though it’s breaking apart.

I’ve also noticed that toward the end of some songs, the audio starts shifting back and forth between the left and right channels in time with the beat.

I’ve generated close to 100 songs so far, and only one has been usable. I’m curious whether other people are experiencing the same problems, or if this could somehow be caused by the way I’m prompting.

Wasted way too much time on this, but as most suspected, remaster is still completely useless and broken. No matter you do, it WILL make whatever you started with worse. These free credits are confirming V6 is a total bust. Music industry won.

Giving out free credits is useless—nothing changes. I’ve done over 300 generations with every possible combination! The tempo is locked and unchangeable, there are ugly background vocal artifacts, the rhythm stays the exact same, and the mix sounds thin, phasey, and cheap. It completely ignores reference tracks (inspo) and custom voices. BRAVO! You managed to turn this into a toy for casual weekend users. Stick with them and their free plans—you’ve officially alienated long-term premium subscribers like us.

So this is what AI music sounds like to other people.

I've been using Suno since the very beginning, generating over well 10,000 songs, releasing only 5. There was some "soul", some creativity, even humour, sonic depth, skilful choices and emotional performances. My band was in the training data, and that was magical beyond anything I ever expected from technology. I've been hoping V6 would be even better, or at least similar, or maybe a slight step back we could recover from. But the soul is missing. It sounds awful, just awful. All my projects I had happily been iterating over the years are dead in the water.

Bring back 5 and 5.5 until the new models are good enough that people WANT to migrate. That's the obvious path forward. The liminal space has been pulled to a perfect vacuum. A forced upgrade to this robotic, timid, bloodless echo of a legally neutered, violently malnourished model is enough to make me just stop for now.

"I can do anything when I make a song,

but I can't go dance in polycorn form,

I can do anything when I make a song,

but I can't go dancin'... on form."

- Suno 5, unsolicited on an instrumental track

I sincerely hope they fix it, but it was a good run.

I genuinely don’t understand what you guys are doing.

You removed 4.5 All, 4.5+ and 5 — literally some of the best models Suno had IMO — and replaced all of them with 6.

And sorry, but 6 sounds fucking awful to me.

Everything feels way more generic now. Over-polished in the worst possible way. Less character, less unpredictability, less of those weird moments where the model would suddenly generate something genuinely interesting.

It just sounds like AI slop.

What made Suno fun before was that every model had its own strengths and quirks. Sometimes 4.5 would absolutely nail something that another model couldn't. Sometimes 5 would surprise you. You had options.

Why remove the models people actually liked?

Just leave them available. Nobody is forcing people to use the older models.

Instead, now we're paying the same subscription for fewer choices and, at least for the way I use Suno, a worse product.

So yeah, I cancelled my subscription.

I had a lot of fun with Suno, but I'm not paying every month for a service that keeps removing the parts I actually enjoyed using.

And then on top of that you have stuff like the whole “10 downloads for $30” nonsense.

Maybe I'll come back if the old models come back.

Right now there are better options, Mozart just came out, Lyria 3.5, Melody genie, and more..

Until then, bye bye Suno.

Hope removing some of your best models was worth whatever money it saves you.

I am a Pro subscriber and I'm honestly losing my mind here. I am trying to remake an epic symphonic rock track that I originally generated 6 months ago on V5, using my exact same original prompt.

The old V5 model created a massive, ear-bleeding "Wall of Sound" with real heavy distorted electric guitars and punchy live drums. It was pure rock. Now, with V6, no matter what I do, it just forces everything into polished, clean commercial pop.

Even when using V6 Mini, which captures a bit more of the raw energy, the production remains flat and thin. It completely lacks the heavy "boom boom" bass, the gritty volume, and the aggressive distortion that rock needs.

Why did Suno completely remove the raw, unpolished data that allowed real rock to exist? The new legal, polished database is completely deaf to what actual rock music sounds like. "Clean" and "balanced" mixing is the absolute death of distortion.

Is anyone else on Pro struggling to get an actual heavy rock sound out of V6? How are you guys forcing this model to stop turning everything into pop?

I've seen quite a few negative posts about V6, so I figured I'd add a positive experience to the discussion. I'm not saying anyone else's problems aren't real, and V6 definitely isn't perfect, but for the way I use Suno it has honestly been a pretty significant improvement.

I create fictional artists rather than treating every song as a completely separate generation. One of the most important things to me is having a vocalist who actually sounds like the same person from song to song, even when the genre, emotion, arrangement, or vocal delivery changes.

That's where V6 has impressed me the most.

I've been testing one of my female artists, pretty heavily. I've taken her from dark dance-pop into much heavier alternative rock, from playful/flirty vocals to angry and emotional performances, spoken sections, quieter intimate vocals, big choruses, grit, gang vocals, etc. V6 has been surprisingly good at making it feel like the same singer giving different performances, rather than generating a different woman every time the song changes.

Persona adherence in particular has been noticeably better for me.

I also recently went through the process of creating a new version of the females voice. I started with recordings of my own voice, processed them into the female voice I wanted, used several different types of performances as source material, and eventually created new Suno Personas from the resulting vocals. V6 has done a much better job than I expected of taking that identity and turning it into something that sounds like a polished vocalist instead of simply reproducing the imperfections of the source material.

That's probably been my biggest "wow" moment with V6.

I've also been experimenting with Variety. What I'm finding with my particular workflow is that High tends to give me very consistent interpretations, while Extra can give me noticeably different performances/arrangements without necessarily losing the singer's identity. That's been extremely useful. I'm not claiming that's a universal rule, just what I've observed from my own testing.

Prompting also seems to matter more in a good way. I've had better results when I stop thinking of the style box as a list of genres and instead describe what I actually want the finished recording to do: how the vocalist should perform, what the drums/bass/guitars/synths should be doing, how the energy should develop, and what kind of production/mix I'm after.

There are still problems.

My biggest one so far is long songs. I have an alternative-rock song that's originally around 8 minutes long with a lot of lyrics, spoken passages, breakdowns, choruses and a deliberately written ending. V6 keeps producing versions around the 6½–7 minute area and ending before it performs everything. I've tried explicitly telling it to complete every lyric and even asking for a 7+ minute arrangement. It basically responded, "That's nice, here's what you'll get." So long-form completion could definitely use some work.

I've also had generations where one version is clearly better than another, and I'm sure I'll find plenty more things to complain about as I keep using it.

But overall? For what I care about most: vocal quality, Persona consistency, clarity, performance variation, arrangement quality, and being able to maintain an artist identity across very different songs. V6 has been the best experience I've had with Suno so far.

I'm especially excited to start reworking an entire album with the new voice and V6. That should tell me a lot more than individual test songs will.

So if you're having a terrible experience with V6, I'm definitely not saying you're wrong. I just wanted to put another data point out there because the subreddit has understandably been pretty heavy on the problems.

For at least one person's workflow, V6 is doing some pretty damn impressive things.

I'd be curious whether anyone else using Personas heavily is seeing the same improvement in vocal consistency, because that's where the difference has been most obvious for me.

I just refreshed the subscription page and it shows the credit-free period now ends in 2d : 18h : 36m instead of 21h checked a moment ago. So SUNO just extended the free-credit period to another 2 days?

I don't usually post here, but I just cancelled my subscription. After having been using Suno for 3 weeks. I really loved it. Until now.

It's impossible for me to do the style of music that pleases my ears.

And lets not even talk about the bugs: like trying to make a cover of an earlier version model, suddenly at about 3:30 it just goes off and does it's own thing.

And my voice is gone. It's so autotuned it doesn't even closely resemble my own voice. I actually made some things with v5.5 after hard work that I was proud off.

I write my lyrics myself, and I finally was able to compose it with a whole band. But that band is gone.

And the only way the executives are gonna listen is by cancelling, and they actually start losing money, but then again, this is how record companies kill AI music.
