AI Music Generator Comparison 2026 (Chartlex)
Chartlex’s comparison of the leading audio-music-generation platforms — the founding music-gen source, notable for foregrounding the ai-music-copyright fault line.
The field
| Tool | Vocals | Instrumental | Note |
|---|---|---|---|
| suno v5 | best-in-class | strong | full songs from one prompt; Elo 1293; $2.45B val / $300M ARR / ~2M subs |
| udio | strong | excellent | hi-fi stems; hip-hop/R&B/pop; “cleanest legal posture” |
| ElevenLabs Music | excellent | strong | multilingual; modular section regen |
| stable-audio | none | excellent | sound design; up to ~3–6 min @ 44.1kHz; open weights |
| AIVA | none | strong | cinematic/score; MIDI export; full copyright ownership |
Pricing (Apr 2026)
Suno Pro $10 / Premier $30; Udio $10 / Pro $30; ElevenLabs Music $9.99; Stable Audio free (non-commercial); AIVA Pro €49 (full copyright).
Licensing is the dividing line (ai-music-copyright)
- suno: Warner settled late-2025; active Sony litigation (ruling ~summer 2026); training-data legality contested.
- udio: UMG settlement (Oct 2025) + Warner/Merlin/Kobalt; a joint UMG-licensed platform in 2026 — the clean story.
- stable-audio: trained on licensed AudioSparx data; clear commercial framework; no known suits.
- AIVA: public-domain-heavy; full IP ownership on Pro.
A sober note
Chartlex’s 2,400-campaign analysis: AI tracks appear in ~18% of indie catalogs but show 25–40% lower save rates / 15–25% higher skip rates than human recordings. Verdict: AI for demos/sketches, finish with humans.

Superseded on rankings, and it set the cast (added 2026-08-03)
Its Elo figures are superseded by music-arena-leaderboard (T2, neutral): this survey’s “suno v5 ~1293” has no counterpart on that board, where Suno V5 scores 1158 instrumental / 1097 vocals — a gap too large to be drift, so read it as a different scale.
The more consequential problem was not a number. This survey supplied the wiki’s entire cast for audio-music-generation — suno, udio, stable-audio — and omitted mureka, which holds ranks 2 and 3 on both current boards. It also framed udio as the close rival, where the board puts it 16th of 18. Tier discipline discounts what a T4 source claims; it does nothing about what a T4 source leaves out. Recorded in synthesis as the reason to hold a neutral board for any branch this wiki ranks.
