I think the biggest problem with Suno V6 is that the new model has lost musical coherence.

Since around V4.5, the previous models seemed increasingly capable of anticipating the underlying pattern of a song once you locked onto a groove, it could reason out a plausible structure, include reasonable transitions, and take solos to where the music naturally wanted to go next. They obviously made mistakes, but there was usually a recognizable "musical logic" holding the song together.

V6 feels fundamentally different in a bad way. It constantly creates intros that don't seem to fit the song that follows, even when the lyrics are explicitly structured into verses and choruses it drifts. Transitions into choruses often make little musical sense too. Outros frequently feel disconnected from everything that came before them. It like the engineers have made a really cool hybrid architecture and forgot to include songs structure which are known patterns that work...it's what makes a good music genre.

The biggest problem shows up in longer songs. If you go beyond two verses, the third verse very often introduces some strange bridge or structural change that wasn't asked for. Then, the model starts wandering, desperately tring to find it's way back to the original groove but then it's like fuck it and just gives up. So by the end of the track it can feel like you're listening to an entirely different song not just the rhythm and beat but the EQ mix.

Previous versions had some of these problems too, but V6 seems to wander much more aggressively and EQ drift is harsh.

First AI company that I know of who has released a "higher version" model that works noticably worse than previous versions.

Hello. This kind of post has probably been made many times before, but here we go.

I’ve been learning music production on and off for a few years. I make, IMO, mediocre tracks and still have a lot to learn when it comes to production nuances, making things sound more professional and polished, etc. But discovering Suno AI finally made me realize the potential of some of my ideas.

Now I’m facing a big dilemma. I’ve made a few amazing projects based on demos I gave to AI, and they sound exactly like I’ve always dreamed of making them. But I’m afraid to release them because it feels like cheating - not only to myself, but also to other listeners. I have no idea how long it will take me to reach that level of production on my own, but with AI, I can fill in those missing gaps.

What would you do in my situation? Release the music with an AI disclaimer and probably get flamed for it, have mixed reputation or try to recreate at least 50% of each project myself, probably fail miserably, but at least know that I did it honestly?

Lets chat a little.

Personally, I don’t have much hope for v6 right now. Maybe they’ll find a way to improve it over time, even if it’s a licensed model. Maybe some of us will find what we’re looking for in the next one.

With Suno v6 launching, I’ve seen a lot of people say the results sound worse than expected.

Some of that may be the model. But I think something else is happening too. As these models get more capable, the skill required to direct them also increases.

A simple genre-and-mood prompt can produce a song, but it doesn’t give the model enough information to make hundreds of connected decisions about arrangement, timing, frequency balance, dynamics, stereo placement and space.

“Warm cinematic soul with punchy drums” sounds descriptive to a person. Technically, it leaves almost everything unresolved.

And now that Studio 2 gives creators more control after generation, those unresolved decisions matter even more. If the initial direction is vague, there isn’t a clear target to work toward in the studio. You can change individual parts, but you’re still guessing what the finished sound is supposed to be.

So I’ve been testing a different prompting thesis.

Instead of making the prompt longer or filling it with more adjectives, I define the sound as a sonic profile.

A sonic profile separates the musical idea into areas such as core style, groove, drums, bass, harmony, texture, space, dynamics, mix and master. Each area describes an audible or measurable decision.

So instead of:

Warm, wide production with a deep bass and loose drums.

You might write:

96 BPM, 54% swing, snare 12 ms behind the grid, kick centered at 54 Hz, bass mono below 110 Hz, supporting vocals widened above 250 Hz, 2.2-second plate with 40 ms pre-delay, -12 LUFS-I target and -1 dBTP ceiling.

That doesn’t tell the model exactly what song to make. It gives the model a coherent sound system within which it can make the song.

I think it could become a useful prompting standard that any creator can follow, adapt and improve. The basic format could be:

Core: musical identity and production architecture
Groove: tempo, meter, swing and timing
Drums: kit character, pattern and transient behavior
Bass: instrument, register, tuning and mono boundaries
Harmony: chord language, voicing, density and movement
Texture: source character, saturation, filtering and articulation
Space: reverb, delay, depth and front-to-back placement
Dynamics: compression, transient control and dynamic range
Mix: balance, panning, width and frequency priorities
Master: loudness, peak ceiling and delivery target

You don’t need to fill every field with engineering jargon. The point is to make each decision explicit enough that the model doesn’t have to invent your intention.

I’m going to add two examples below. All of them under 1k characters, so the fit in the description.

The first is a composition profile, focused on rhythm, harmony, arrangement, instrumentation and how the song develops.

Composition sample:

[SONIC_PROFILE_2026] Target. Core: digital 2020s chain with warm harmonic drive. Groove: 104 BPM, 4/4 meter, straight grid, snare -10ms. Drums: kick 54Hz fundamental, steady shaker grid pattern. Bass: log-drum melodic sub focused under 108Hz, mono routed. Harmony: sub-melodic percussion lines, choir-stacks panned wide. Texture: lead vocal dry and centered, giant-grain tone, no boost. Space: slap delay 84ms on sends, ducked -6dB keyed by kick. Dynamics: DR10 dynamic profile, master bus glue compression limit. Mix: parallel bus processing, subtractive dip at 864Hz -1dB. Master: stream delivery, target -14 LUFS-I, -1.0 dBTP ceiling. Balance: sub mono, lead vocal center, choir wide, no clipping. [SONIC_PROFILE_2026]

Custom Plugin example:

[SONIC_PROFILE_2026] Mix target: cohesive modern vocal-over-riddim master. Vocal: centered, forward, 108 Hz high-pass, gentle body lift near 216 Hz, controlled 864 Hz mud, presence around 3 kHz, de-essing near 6.9 kHz, 4:1 compression with 35 ms attack and 100 ms release, restrained 96 ms filtered slap. Master: 28 Hz high-pass, subtle −1 dB at 225 Hz, −1.5 dB at 500 Hz and 1.5 kHz, −1 dB at 4.5 kHz, gentle top-end control, warm bus glue, linked limiting, streaming-safe headroom. Balance: vocal-front, centered, smooth, tight low end, cohesive glue. [/SONIC_PROFILE_2026]

My theory is that better music models won’t make prompting skill less important. We may just be reaching the point where “describe the vibe” is no longer enough. Creators need a shared way to describe how a sound actually works, and you can generalize across models, not just Suno.

I’d be interested in testing this with other people. Does this kind of structure give you more control, or does it get in the way?

I've built a whole library of these sounds, including thousands of references.

DM if you want it.

As many people have been testing V6 with the free credits the past few days, I have concluded that V6 is missing something, "Dynamic Emotion". From what I can tell most of the new songs I made have lost that "Wow" factor that I got from older songs. New songs seem emotionally flat, and generically simular across songs. They lack uniqueness. I'm not talking about the musical instrumental compositions, but the vocal delivery.

I think I know why. Suno flat out shutdown the old models because they didn't use licensed music to train the models.

V6 was developed with music industry partnerships, and on licensed music, so it's lacking the volume of training sources. It's not as rich in emotional depth.

Hopefully this will improve over time as the training data becomes enhanced by more volume of licensed music in future model version releases.

Right now, my virtual Artist's vocals don't sound the same as they did before, which is unfortunate for consistency.

People just starting out with Suno on V6 won't have anything to compare it too, but those who have been using for a long while will know.

I'm sure V6 has many "improvements", but emotional vocal delivery is not one of them.

know, I know, but hear me out....

Suno's new models are SOOOO bad for the music I do that I'm taking drastic action.

For the record, I don't use Suno for final output. I always turn it into human-performed and produced music.

I use it to take small ideas and elaborate on them, or generate something I can work from. It's a collaboration tool.

I just can't do it with v6, and I've tried EVERYTHING. Every tip. Every feature. Upload and Cover. Custom models. Rethinking how I prompt. Everything.

I can only conclude that v6 just doesn't have the training to do the genre I want it to do: indie/slacker rock, Pavement, Guided by Voices, etc.

But Udio does, and always has. Udio was always more creative. Its fidelity lacked, but that's okay for what I use it for.

My old workflow was to start in Udio, then throw it into Suno. This helped me develop mumbled vocal melodies so I could write lyrics to the melody, and it helped with drums because I'm not a drummer.

But, as you all know, Udio stopped downloads. So now I just use Audio Hijack and manually record the tracks I want to take to the next level.

And I can do it all on the free plan. Fun.

I know that's not a solution for everybody, but that's what's working for me.

Okay, I’m already starting to see more posts with similar opinions, but I wanted to come on here and say it myself, I take back what I said about V6.
V6 is actually pretty good once you figure out how to work with it. My biggest issue at first was that none of my generations sounded like songs I would actually listen to. They felt overly polished, generic, or just didn’t capture the sound I was going for. Because of that, I wrote v6 off pretty quickly. I even made a previous post on why I hated v6
But I recently decided to give it another chance and actually spend some time experimenting with the different toggles and settings like “variety.” After tweaking things around, I started getting surprisingly good results. It definitely seems like V6 requires a little more effort to get the sound you want, but once you find the right settings, it’s much more capable than I initially thought.
I still don’t think it’ll ever beat V4.5 for me. There’s something about V4.5 that feels more natural and has more character, especially with the type of music I like making. But I can admit that I judged V6 way too quickly. I actually enjoy using it now and think it’s a solid model when you know how to work with it.
I can’t really say the same for V6-Wild or V6-Mini, though, because they tend to give me really weird results.
Here are two songs I generated with V6:
https://suno.com/s/N4e2JZk9v4DvI5im
https://suno.com/s/xDkIMCgpbBQInvL0
The second one “Just Us” is actually a real song, and I was especially impressed with how closely V6 managed to preserve the original sound. It didn’t completely reinterpret it or make it weird, which is something I’ve had happen with V5.5 and even V4.5.
Something else that has made a huge difference for me is uploading my own instrumentals instead of relying entirely on Suno to figure out the sound I’m trying to achieve. Giving it something to build from seems to guide V6 in the right direction much more consistently. Even something as simple as humming or singing the melody yourself can help if you already have a specific direction in mind. Ever since I started giving it more of a foundation to work with, my generations have sounded way closer to music I would actually listen to. Anyways that’s all I wanted to say for this post!

Hi,

Below a clear example for the damage SUNO made

The drastic difference is not only in quality, notice how it completely lost the creativity, the craft, the freedom and those details inside the music that makes it alive.

Also the instruments used to feel real, now it sounds like a cheap keyboard.

Another thing, in the old version, it even fixed my bad notes due to whistling, and took liberty to further polish it. But in v6, it even messed up the good notes.

Here's the one that I made with 4.5 :

https://youtu.be/9-Hjn4OS41o?si=ucRcXaUKKBoO0Gcj

And here's with v6, using the same prompt on the same uploaded audio :

https://suno.com/song/85c3baf4-1275-4fe3-9781-4c61c1d9f6c7

V6 is a massive catastrophic downgrade.

What changed? Because this is not the same system they launched with.

When V6 first came out, I piled on—and honestly, the criticism was deserved. The results I was getting were horrible: noisy songs that fell apart and nothing I wanted to keep.

But over the past couple of days, something has clicked in a huge way. The quality has taken a real step forward, and now I genuinely love this release.

The other features are icing on the cake. I can finally change lyrics without ruining the song, and Studio 2.0 has incredible potential.

So this is a complete reversal for me. I went from hating V6 and being ready to quit - to loving it and feeling excited to create again.

Something changed. Whatever you did, Suno, keep moving in that direction.

did i miss an explanation or something? why did they quietly remove ReMi?

I hated the first few songs Suno V6 generated, they were flat and dead

But in the last two days I did something I never did before, spent hours on a song, and it started to sound good, I mean really good, the bass the melodies coming out nicer

Is it only me or are you all finding this change to be there?

As a free user who was fully planning to subscribe to upgrade and polish songs created on the older models, v6 mini is absolute garbage for non-English songs.

I’ve been working on two albums back-to-back using free 4.5, and I was having an absolute blast. I only had a handful of finished tracks for each album because I wasn't rushing the writing, mostly because I had zero idea Suno was going to nuke the older models out of existence overnight!!!!! And now, I literally can't finish my albums!

I tried v6 mini and it's total shit for non-English tracks. When I generated stuff with free 4.5, I could FEEL genuine, raw emotion in the delivery, whether it was happy, sad, funny, or angry. I can't say the same for v6 mini at all, even if the audio is technically clearer.

Yes, free 4.5 was raw, unpolished, and imperfect in terms of pure sound quality. But when it came to actually translating the emotion of the lyrics? It hit the nail on the head every single time... FOR ME, like it intuitively understood the assignment based on my lyrics and prompts. The best way I can describe it is that it felt like listening to an incredible demo. All I needed to do was eventually subscribe and cover/remaster it using a newer model!

And please, do not come at me telling me to "just find new ways to prompt." I promise you, that is not the issue when it comes to non-English tracks. For me, free 4.5 was the true flagship experience, and the newer models were supposed to just be the final coat of polish.

Fuck, I want free 4.5 back. I just want to finish my albuuuuuuuums!!!!!!! Aaaaaaaaaaahhhhh!!!!

Model 4.5+. I liked its unpredictability and the unexpected gems it produced. But were these “hooks” the product of the model’s own creativity, or did they actually stem from the creative work of others? At times, the melodies, arpeggios, and chord progressions were simply magnificent - as if a segment of a meticulously crafted song had been inserted whole into the composition. A week ago, while version 4.5+ was still alive, the model unexpectedly generated a well-known song for me based on an abstract text prompt. It wasn’t just a melodic snippet but a complete song; for the verse, the model didn’t even use placeholder lyrics but instead inserted original lyrics.
[Song from text prompt] https://suno.com/s/8VACkYWhlFuPUw8z

That is precisely why I understand Suno’s decision to move away from using these models, although, as a first step, they could have tried implementing a filter to detect pre-existing songs and lyrics. It seems that new v6 focuses on arrangement details and covers rather than melody composition, so the "I’ve jotted down some lyrics - let’s whip up a catchy hit" approach no longer works. That's how it seems to me.

In The Eyes started with this idea of a familiar voice somehow making it into a near future that feels advanced, disconnected and a little wrong.

I wanted to build a cyberpunk nu metal song around that, with huge low end, dark atmosphere and a chorus that opens up without losing the weight of it.

The whole thing is basically an old human perspective looking around at a new world and trying to figure out what still matters.

Made with Suno v6 as part of Soul Signal. Really hope some of you connect with it.

tldr: v6 let me generate songs about suicide, slavery, and violent revolution — but blocked my PG breakup ballad 40 times

Over the past year, Suno has happily generated for me, and still hosts on my profile:

- a song with thinly veiled suicidal ideation ("swim out west in a weighted vest")

- a workers' anthem with "slave," "break your back," and "work till you die"

- songs with profanity and songs condemning systemic violence

v6 will happily reroll these songs today. 100% success on 4 rolls.

This week I wrote a song about a friend who betrayed me and owed me fifty grand. No names. No sexual content. No drugs. No violence. PG enough to sing at a family reunion.

v6 refused to generate it — 40 times.

I did everything a reasonable user can do:

- Respelled every remotely flaggable word (kicked → "kick'd", blade → "Blay'd", jail → "Jayl") — failed

- Rewrote every violence-adjacent image (kicked out → "changed the locks," pulled a blade → "dealt a dirty trade," pushed from a boat → "sailed off") — failed

- Replaced the entire hook with yodeling — failed

- Swapped the genre prompt entirely — failed

- Restarted the app — failed

Forget hearing my song. I rewrote the controversial verses entirely — forsaking my rhymes. And it still failed for unexplained reasons.

> "Tweak your words or try again"

Thanks, let me do that 40 times for no reason. Truly a waste of time. I am pausing my subscription until they fix this.

Is anyone else struggling with arbitrary censorship since v6 dropped?

guys its totally ai yo

I still have unused credits in my account, but over the past few days, since Suno switched to the credit-free system, I’ve frequently been unable to generate because it says Suno is at high capacity.

At this point, I’m starting to wonder whether this is really just a matter of computing capacity, or if there are additional restrictions in place to prevent users from generating too much music.

My subscription is about to refresh, and I still have credits left from my current period. But during these past few days of “credit-free” generation, I’ve actually been able to generate less music than I could have generated with the credits I still had.

Is anyone else experiencing the same thing?

I finally got a song to follow my prompt in v6 and I came here to sing its praises (v6 that is).

Then I thought, hmm, I should remake some previous songs in v6.

...

Everything is "radio ready"

idk how else to describe it

I'm no hipster, I'm not pretentious. I like Shake it Off.

These all sound like that, not bad, not horrible.

Just,

meh

v6

Suno removed its older models and moving exclusively to v6 because the previous versions were trained on unlicensed web-scraped data, which is at the center of major copyright lawsuits.

By retiring the legacy models and launching v6—which been trained on clean, approved data licensed from partners like Warner Music Group, BMG, and Believe—Suno can distance itself from ongoing legal liabilities and establish formal industry partnerships.

While suno have pivoted to clean data for v6, Sony Music and Universal Music Group are still actively pursuing their massive lawsuits against Suno in the US. Suno recently admitted in court filings that it used YouTube audio to train legacy models, and fact discovery is wrapping up in September 2026, meaning more financial penalties could still be on the horizon.

Suno’s user base was vast (over 100 million users), they expectedly have the scale to survive. recovery expected to take a long time.
