You type a sentence, wait a minute, and get back a track with vocals, drums, and a chorus. That's what AI music generators promise, and the promise has held up since 2024. The real question isn't «does it work» anymore, it's «which one should I 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 track length or commercial rights.
This comparison walks through the options worth your time, with pricing, real-world limits, and what you're actually allowed to do with the result. You'll start with the approach that lets you compare several generators without stacking up subscriptions, then go tool by tool. By the end, you'll know which one to open tonight based on what you need: background music for your videos, a song demo, or an instrumental to build on.
Approach 1: compare generators from the Skilzy AI Lab
If you're torn between three tools, the cheapest move is to use an environment that already includes music generation, rather than paying for three subscriptions in parallel just to form an opinion.
That's the idea behind the Skilzy AI Lab: credits are included in the subscription, you generate your tracks directly in the platform, and you're not juggling four monthly charges in dollars. In practice, you type your prompt, listen, adjust, and compare results without starting over every single time.
The real difference is the guidance. A raw generator hands you an interface and leaves you to figure it out; that's where 90% of beginners quit, after three failed tracks that sound like a karaoke demo. The Compose a Hit with AI program comes at the problem from the other direction: writing a style prompt that actually describes a genre, structuring a track (intro, verse, chorus, bridge), placing structure tags, handling lyrics in your language to avoid weird stresses, then exporting cleanly for a video or a streaming platform.
Skilzy brings together more than 15 programs of the same kind (images, UGC videos, faceless channels, voiceovers, automation with n8n, prompt engineering) plus two state-recognized, fundable certifications: RS7439 in AI content marketing and RS6792 in AI and sales. Subscriptions start at €29.90/month with no commitment.
To get a feel for it before paying, the discovery demo runs with no credit card: 7 days with 1 image, 1 video, 1 music track, and 10 messages. It's deliberately limited, but enough to see what your idea sounds like turned into a track.
Let's be honest about the scope: if you need to crank out 300 tracks a month, a dedicated Suno subscription is still the better fit. If you want to learn how to produce a track that actually holds up and use it in your content, the guidance changes the outcome far more than the underlying model does.

Approach 2: 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's the generator that took this whole topic mainstream, and it holds a lead on three fronts: structural coherence (choruses actually come back around), stylistic range, and the ecosystem built around generation. You can upload an audio clip to extend it, separate stems (vocals, drums, bass), create a reusable vocal «persona» across tracks, and tweak a specific section without regenerating everything.
On pricing, everything runs on credits. The free plan gives you 50 credits a day, a generation costs 10 and returns two versions of the track, so you get roughly 10 tracks 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: non-English languages are decent, but word stress sometimes lands in the wrong place on long words; the mix comes out compressed, a bit «FM radio», which you notice next to a human production; and past three or four minutes, tracks often start looping. If you want to explore other options, we've broken down several Suno alternatives.
Approach 3: Udio, the pick for picky ears
Udio often delivers 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 gives you a complete track on the first try, Udio works 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 track without losing the rest. Users coming from DAW-based production appreciate that build-as-you-go 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 around it, or you may end up with tracks you can't get out of the tool.
Short version: Udio for sound quality and fine-grained control, Suno for speed and freedom of use.
Approach 4: 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 sector's best surprise, 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, strong on Asian languages and instrumental generation, with an accessible API for anyone who wants to plug music generation into an automated scenario (n8n, Make).
- ElevenLabs Music: launched in 2025 by the synthetic voice specialist, with licensing deals signed with publishers. It's currently one of the legally cleanest choices for commercial use, with very crisp vocal results.
- Stable Audio, Soundraw, AIVA, Beatoven: these four aren't trying to write songs, they make royalty-free instrumental background music calibrated for video and podcasts. You pick a mood and a length, and you get a track you can use without risking a YouTube claim. No vocals, no lyrics, and that's exactly the point.
If your goal is more rhythmic than melodic, take a look at how to make a beat with AI without knowing how to produce: the prompting logic isn't the same as for a song.
The comparison in one table, and how to choose for your use case
There's no best generator in the abstract: there's 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 |
|---|---|---|---|---|
| Skilzy AI Lab | Generation + learning, credits included | Not built for industrial volume | Yes | 7-day demo, no credit card |
| Suno | Complete songs, rich ecosystem | Compressed mix, imperfect non-English | Yes | 50 credits/day, personal use |
| Udio | Acoustic feel, 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 licenses, 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 fast:
- 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 instinct, Udio if the style calls for real acoustic textures.
- Test a lot, decide later: Riffusion for volume, or the Skilzy AI Lab if you also want to learn the method.
- Automate steady output: Mureka or Suno's API, wired into an n8n scenario. That ties into automating social media publishing.
What you're actually allowed to do with your AI music
Commercial usage rights almost always depend on your subscription: on Suno's and Udio's free plans, tracks are for personal use only, and monetizing requires a paid plan.
Second point, often misunderstood: under both French and U.S. law, a work generated purely by a machine, with no meaningful human contribution, doesn't get copyright protection. You can use your track if your subscription allows it, but you'll 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're detecting and flagging it more and more. Deezer reported in 2025 that fully AI-generated tracks were making up a fast-growing share of its daily uploads, rising 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 release with no editorial work behind it has no chance of standing out.
Finally, register your works properly. France's SACEM has set up an opt-out for AI training data and asks you to disclose the use of generative tools when registering. If you're 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 doesn't 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 only one variable each time (style, then tempo, then structure), and compare. It's the fastest way to understand what these generators can do, and what they still can't.
