An AI music generator turns a line of text into finished audio, but the tools behind that promise split into two very different camps. Some build a complete song — vocals, verses, choruses, and a hook — while others specialize in royalty-free instrumental beds you can drop under a video or podcast. Picking the right AI music generator comes down to which of those two jobs you actually need, plus three practical details creators keep getting burned on: vocal quality, how much you can generate on a free tier, and whether the license lets you sell what you make.
This guide compares five real generators for exactly those trade-offs. If you also need to write the words your track will sing, pair this with our roundup of AI lyrics generators; if you want a specific voice rather than a full song, see our guide to AI singing voice and voice cloning. All five live in our directory of AI song generators.
Full songs vs royalty-free beds: what an AI music generator is really for
The first fork is the most important one. A full-song tool composes structured tracks with sung vocals and lyrics — the output feels like a release you could put on Spotify. A royalty-free bed tool is tuned for background music: loopable, mood-driven instrumentals sized to sit under narration without fighting it. A few platforms straddle both. Deciding which side you land on narrows the field faster than any feature list, because the tools optimized for radio-style vocals rarely give you the tidy 30-second instrumental loop a video editor wants, and vice versa.
What to weigh before you commit
- Vocal quality & style control: can you steer genre, mood, tempo, and the voice itself?
- Commercial license: is the music yours to monetize, and on which plan?
- Free-tier generation caps: most tools meter output with credits, so the free plan sets how much you can actually make before paying.
- Stems & editing: whether you can pull vocals and instruments apart for a real mix.
The best AI music generators for full songs with vocals
If you want a complete track that sings, two names lead the category.
Suno
Suno generates full songs with vocals and instrumentation from a text prompt, and it goes further than most on editing. Its Suno Studio DAW handles remixing and stem extraction, exporting up to 12 time-aligned WAV stems into Ableton or Logic — the difference between a locked demo and something you can actually mix. Style control is granular: voices, exclusions, vocal gender, and even "weirdness" sliders. On pricing, Suno runs a Freemium model; the Pro plan is $8/mo for 2,500 credits with commercial rights, and Premier is $24/mo for 10,000 credits plus Suno Studio access. The catch worth flagging: commercial usage rights land on the paid plans, so anything you intend to sell should be made under Pro or higher.
Udio
Udio creates music from text descriptions in seconds and leans into vocal-forward, genre-guided generation. Beyond the initial clip, it offers song extension and remixing tools, so you can grow a short idea into a longer arrangement rather than re-rolling from scratch. There is also a large library of user-generated tracks to explore for inspiration. Udio uses a Freemium model; treat its free tier as a place to test whether its vocal style matches your taste before committing.
Royalty-free beds: an AI music generator for background tracks
When the goal is music that stays out of the way — under a YouTube voiceover, an ad, or a game scene — a royalty-free-first generator is the better fit. These three are built for exactly that use.
Loudly
Loudly is a royalty-free music platform with text-to-music generation plus a library of tracks and stems. It bundles a song remixer, a sample-pack generator, AI mastering, and a stem splitter, and it can distribute finished music through its API. One detail that matters for cautious brands: Loudly states its model is trained on an ethically sourced dataset, which reduces licensing anxiety for commercial use.
Mureka
Mureka handles text-to-music with adjustable genre, mood, tempo, and instrumentation, and outputs royalty-free downloadable tracks. It runs on credit-based generation and adds custom soundtrack tools, making it a flexible pick for filmmakers and game developers who need scored cues rather than songs. Mureka is Freemium with a free trial to test the workflow first.
Musicful
Musicful positions itself around free, copyright-free songs and is unusually broad in inputs: it generates from text, lyrics, or even a hummed melody. The toolkit also covers an AI music video generator, AI covers, a beat maker, a stem splitter with vocal isolator, and WAV plus MIDI download. For content creators and podcasters who want background music without a licensing headache, that copyright-free framing is the draw. It is Freemium with a free trial.

Free plans, credits, and commercial rights
Every tool here is Freemium, but "free" is metered. Generation is almost always credit-based, so the real question on a free tier is how many tracks you can produce before the meter runs out — test that limit against your actual project size before you rely on any one platform. Licensing is the other trap: Suno grants commercial usage rights on its paid plans specifically, while Loudly and Mureka center on royalty-free output and Musicful on copyright-free songs. If you plan to monetize, confirm the commercial terms on the exact plan you intend to buy rather than assuming a free download is safe to sell.
Which AI music generator should you choose?
For a released-quality track with vocals and hands-on editing, start with Suno; if you prefer Udio's vocal character, its extension tools make long-form arrangements easy. For background beds, Loudly and Mureka give you royalty-free, mood-controllable instrumentals, and Musicful is the widest net for copyright-free creator music. Once you have the music, close the loop with our AI lyrics generators guide, or dial in a specific singer with AI singing voice and voice cloning.
