How to choose an AI music generator: seven questions that matter more than the demo

Choose an AI music generator by reading its license before playing its demos. In 2026 the audible gap between major tools is narrower than the contractual gap: commercial rights start at $6 a month on one tool and never include a streaming-service release on another at any price; some free tiers hand you files and some hand you previews; and what happens to your tracks when you cancel ranges from "yours forever" to silence in the terms. The seven questions below sort the market faster than any ranked list — and they are the questions that hurt when you skip them.

Here is the shape of it, then each question in detail.

#	Question	Tools that answer it well (as of July 2026)
1	Vocals, or instrumental only?	ElevenLabs (vocal songs); Stable Audio, AIVA (instrumental)
2	Which tier grants commercial use?	ElevenLabs from $6/mo; Stable Audio from $11.99/mo — never free
3	Downloads, or a walled garden?	AIVA (3/mo even free); Soundraw and Beatoven free tiers are preview-only
4	Can you release to streaming services?	Soundraw Artist tiers: yes; Mubert: never
5	Stems or MIDI?	AIVA (per-instrument MIDI); Soundraw Artist (WAV + stems)
6	Which languages can it sing?	ElevenLabs (multilingual vocals); PrismPoster (35 languages)
7	What survives cancellation?	Soundraw (perpetual license); AIVA Pro (copyright transfer)

1. Do you need vocals, or instrumental tracks?

This splits the market cleanly. ElevenLabs Music generates full songs with vocals — multilingual, with section inpainting and mid-track genre transitions — and burns 900 credits per minute of audio from a shared credit pool, as of July 2026 (elevenlabs.io/pricing). Stable Audio is deliberately instrumental-only, which disqualifies it for songs but suits scores and beds; its 3.0 release (May 20, 2026) extends tracks past six minutes (stableaudio.com). AIVA runs in a third lane: composition-first and MIDI-native, strongest in classical and cinematic styles, expressively flatter in modern production genres. Mubert, Soundraw, and Beatoven make background music — moods and genres, not songs with a hook.

2. Which tier actually grants commercial use?

None of the major tools grants commercial rights on a free tier, as of July 2026 — start every evaluation there. Then check what "commercial" is scoped to, because it is a scoped word: ElevenLabs starts commercial use at $6/month but excludes film, TV, and studio games on all self-serve plans; Mubert's $14/month tier covers social-media use while full digital commercial rights cost $39/month; Soundraw's ~$11/month tier covers background use only; and AIVA's €11/month Standard tier licenses monetization on a fixed platform list (YouTube, Twitch, TikTok, Instagram) while AIVA keeps the copyright until the €33/month Pro tier (aiva.ai). The word "commercial" on a pricing page is the beginning of the question, not the answer.

3. Do you get downloads, or a walled garden?

Free tiers split three ways: real downloads (AIVA gives three per month, non-commercial with attribution), previews only (Soundraw, Beatoven), and streams without export. The walled garden went mainstream after the 2025 label settlements: the leading consumer song platforms suspended or capped downloads, so tracks live inside the platform — streamable and shareable, but not yours to take elsewhere. If exporting files matters to you, and it should, verify the download policy on the exact tier before subscribing. The legal background is in our AI music licensing explainer.

4. Can you release tracks to Spotify or other DSPs?

Distribution is a separate permission from commercial use, and tools answer it in opposite ways. Mubert prohibits streaming-service release and YouTube Content ID registration on every plan. Soundraw sells DSP release as its Artist tiers (roughly $19–33/month, which also add WAV and stems) — you keep 100% of recording royalties while Soundraw retains the composition copyright, as of July 2026 (soundraw.io). If releasing singles is the plan, this one row of the terms decides your shortlist.

5. Do you need stems or MIDI?

For DAW-based producers this is the sharpest filter. AIVA exports per-instrument MIDI — editable note data you can rescore in any DAW — which nothing else in this guide matches. Soundraw provides WAV and stems at its Artist tiers. Beatoven is WAV-only, with no MIDI. If your workflow ends in a DAW, audition AIVA first; if it ends in a video editor, stems are usually enough.

6. Which languages can it sing?

Background-music tools sidestep this question entirely by having no vocals, which makes it the deciding one for creators working outside English. ElevenLabs is the notable dedicated option, with multilingual vocals reviewers describe as sounding native. PrismPoster's Music Studio writes and sings in 35 languages. If your audience is not English-first, test the language before the genre.

7. What survives if you cancel?

The quiet question. Soundraw's answer is the market's best: tracks made while subscribed stay licensed to you perpetually. AIVA Pro's copyright transfer is durable by nature. Most other tools go quiet in the terms — and across the category, credits are use-it-or-lose-it and failed generations bill anyway, the most common complaint pattern in AI music reviews. Assume nothing that is not written down.

Where does PrismPoster fit?

PrismPoster answers a question this list does not ask: do you want your music tool inside your creation studio? Songs generate at 15 credits each — vocals and lyrics in 35 languages, with stems — next to video generation and a multi-track timeline editor, on one credit wallet. The Free plan includes up to 3 songs a month to test with, and streamers get an approval-first live workflow — you clear every track before it airs, with a Fan Song Queue for viewer requests. The full streaming picture is in AI music for streamers, and the mechanics are on the Music Studio page.

The fit check runs both directions. Pick PrismPoster if your music ends up inside videos, streams, or edits you are also making — the music video workflow is the canonical example — or if you want to release within its ecosystem: paid plans publish tracks to Discover and PrismRadio, PrismPoster's own surfaces. Skip it if you need MIDI for a DAW (AIVA), a copyright-transfer certificate for client work (AIVA Pro), or the absolute cheapest background-music subscription (Beatoven starts at $3/month, as of July 2026). Every PrismPoster export carries embedded AI-provenance metadata, on every plan. And if you are weighing it against the biggest name in consumer song generation, how PrismPoster compares to the biggest AI song tool keeps that comparison current.

Frequently Asked Questions

What is the best free AI music generator?

No free tier includes commercial rights as of July 2026, so treat free tiers as trials. AIVA gives three real downloads a month, Stable Audio gives ten non-commercial tracks, and PrismPoster's Free plan covers up to 3 full songs with vocals each month.

Which AI music generator allows releasing to Spotify?

Soundraw at its Artist tiers is the clearest yes; Mubert is a hard no on every plan, as of July 2026. Everywhere else, check the tier's distribution terms specifically — commercial use and DSP release are separate permissions.

Which AI music generator has MIDI export?

AIVA — it exports per-instrument MIDI you can edit in any DAW, and it is the only tool in this guide that does. Everything else provides audio files, at best with stems.

Are AI music generators safe for Twitch and YouTube?

Original AI music removes the licensed-recording problem behind most muted VODs and strikes, but rights still depend on the tool's tier, and no vendor can honestly guarantee zero claims. AI music for streamers covers the streaming specifics.

What happens to my music if I stop paying?

It depends entirely on the terms: Soundraw licenses tracks perpetually if they were made while subscribed, AIVA Pro's copyright transfer endures, and many tools say nothing — while unused credits expire on effectively every platform.
