You type a sentence, wait a minute, and get back a track with vocals, drums and a chorus. That is what AI music generators promise, and the promise has held up since 2024. The real question is no longer whether it works, but which one to pick. Suno and Udio dominate the conversation, but there are a dozen other serious tools out there, each with its own strengths: some handle vocals better, others instrumentals, others still track length or commercial rights.
This comparison walks through the options worth your time, with pricing, real-world limits, and what you are actually allowed to do with the result. We go tool by tool. By the end, you will know which one to open tonight based on what you need: background music for your videos, a song demo, or an instrumental to rework.
Method 1: Suno, the go-to for complete songs
Suno is still the most complete tool for getting a full song, vocals and lyrics included, from a simple one or two sentence description.
It is the generator that took this whole topic mainstream, and it keeps an edge on three fronts: structural consistency (choruses actually come back around), stylistic range, and the ecosystem built around generation. You can upload an audio clip to extend it, split the stems (vocals, drums, bass), create a reusable vocal "persona" you carry from track to track, and rework one specific section without regenerating everything.
On pricing, everything runs on credits. The free plan gives you 50 credits per day, a generation costs 10 and returns two versions of the track, so you get roughly 10 songs a day for strictly personal use. Paid plans start around $10 a month (about 500 tracks) and go up to $30 for heavy volume, with commercial usage rights. The exact terms change often, so check them on Suno's official help center.
The limits, because there are some: French comes out decent, but the stress falls in the wrong place on longer words; the mix comes back compressed, a bit "FM radio," which you notice when you compare it to a human production; and past three or four minutes, tracks often start looping. If you want to explore other options, we have covered several Suno alternatives in detail.
Method 2: Udio, the pick for demanding ears
Udio often produces a more organic result than Suno on jazz, soul, orchestral, and anything built on acoustic instruments, at the cost of a slower workflow.
Where Suno hands you a full track on the first try, Udio thinks in short blocks that you extend step by step. It takes longer, but you control every transition and can fix a bad stretch in the middle of a song without losing the rest. Users coming from a DAW background appreciate that build-it-up logic; beginners in a hurry find it tedious.
One thing to check before subscribing: following the deal announced in late October 2025 between Udio and Universal Music Group, the platform heavily restricted downloads of generated tracks while a licensed service is in the works. Look at the current export terms on the official site before building a project on top of it, or you risk ending up with songs you cannot get out of the tool.
In short: Udio for sound quality and fine control, Suno for speed and freedom of use.
Method 3: the other generators worth a test
Beyond the Suno versus Udio duel, four families of tools cover needs the two leaders handle poorly: unlimited free generation, instrumentals with clear licensing, background music for video, and an API for automation.
- Riffusion: long the best surprise in the space, with very generous free generation and quality that rivals competitors' paid plans. Ideal if you want to test dozens of ideas without counting credits.
- Mureka: less well known in France, strong on Asian languages and on instrumental generation, with an accessible API for anyone who wants to plug music generation into an automated workflow (n8n, Make).
- ElevenLabs Music: launched in 2025 by the synthetic voice specialist, with licensing deals signed with publishers. It is currently one of the cleanest choices legally for commercial use, with very crisp vocals.
- Stable Audio, Soundraw, AIVA, Beatoven: these four are not trying to write songs, but royalty-free instrumental background music calibrated for video and podcasts. You pick a mood and a length, and get a track you can use without worrying about a claim on YouTube. No vocals, no lyrics, and that is exactly the point.
If your goal is rhythmic rather than melodic, take a look at how to make a beat with AI without knowing how to produce: the prompting logic is not the same as for a song.
The comparison in one table, and how to choose for your use case
There is no best generator in absolute terms: there is a best tool for your specific use, and the deciding factor is almost always whether or not you need sung vocals.
| Tool | Strength | Main limitation | Sung vocals | Free entry point |
|---|---|---|---|---|
| Suno | Complete songs, rich ecosystem | Compressed mix, imperfect French | Yes | 50 credits/day, personal use |
| Udio | Acoustic sound, section-by-section control | Restricted export, slower workflow | Yes | Limited monthly credits |
| Riffusion | Very generous generation volume | Fewer editing options | Yes | Yes |
| ElevenLabs Music | Publisher licensing, very crisp vocals | Narrower style catalog | Yes | Limited trial |
| Stable Audio / Soundraw | Background music with no rights risk | No lyrics | No | Limited trial |
To decide quickly:
- Background music for your videos or podcast: Soundraw, Stable Audio or Beatoven. You want predictable, not spectacular.
- A song with your own lyrics: Suno as the first reflex, Udio if the style calls for genuine acoustic textures.
- Test a lot, decide later: Riffusion for volume.
- Automate steady production: Mureka or Suno's API, wired into an n8n workflow. That overlaps with automating social media publishing.
What you are really allowed to do with your AI music
Commercial usage rights almost always depend on your subscription: on the free plans from Suno and Udio, tracks are reserved for personal use, and monetization requires a paid plan.
Second point, often misunderstood: under French law, as in the United States, a work generated purely by a machine, with no meaningful human input, does not benefit from copyright protection. You can exploit your track if your subscription allows it, but you will have a hard time stopping someone else from reusing it. The more of your own work you add (lyrics you wrote, rearrangement, mixing, real vocals on top), the stronger your position.
Third point: distribution. Streaming platforms accept AI-generated music, but they detect and flag it more and more. Deezer reported in 2025 that the share of fully AI-generated tracks in its daily uploads had climbed fast, from 10% in January to nearly 30% by the fall. The practical consequence for you: your track will probably be identified as such, and a production with no editorial work behind it stands no chance of standing out.
Finally, register your work properly. France's SACEM has set up an opt-out for AI training data and asks you to declare the use of generative tools when you register. If you are aiming for serious exploitation, look into it before you file, not after.
The key takeaway
Suno for a complete song, Udio for sonic standards, Riffusion for testing at volume, Soundraw or Stable Audio for background music with no rights headaches. The real gap in results does not come from the model but from how you write your prompt and structure your track. Open a tool tonight, generate three versions of the same song changing one variable at a time (style, then tempo, then structure), and compare. It is the fastest way to understand what these generators can do, and what they still cannot. You can prepare the text part (the lyrics, the style prompt) in the Skilzy chat before opening the generator of your choice.
