### Suno

> The most popular AI song generator: full 8-minute tracks, the most natural AI vocals, commercial rights from $10/month

Strengths:
- Best AI vocals on the market: v5.5 delivers realistic vibrato, audible breath between phrases and convincing long held notes, ahead of Udio v3.5 in head-to-head comparisons
- Longest tracks of the big three: up to 8 minutes per song, versus 5 minutes for Eleven Music standard generations
- Cheapest full-song commercial tier: Pro at $10/month (2,500 credits, about 500 songs) grants commercial rights, where Udio requires its $30 Pro plan
- Suno Studio (Premier only): a real browser DAW with stem generation and import, timeline arrangement, and export to Ableton Live or Logic Pro; v1.2 added Remove FX and Warp Markers in early 2026

Weaknesses:
- Warner deal fallout: free accounts lost downloads and commercial rights, and paid tiers are moving to monthly download caps with paid top-ups, which users call a bait and switch
- Ownership language was quietly downgraded from 'you own this' to 'you have commercial rights'; reviewers warn against releases that need clean copyright provenance
- Older models are being deprecated when the licensed models ship later in 2026, so a catalogue built on v4.x has an expiry date

Verdict: Suno remains the default buy for anyone who wants finished songs with vocals: v5.5 has the most human voices in the category and the $10 Pro plan is the cheapest commercial-rights entry among serious generators. Take Premier only if you will actually live in Suno Studio and its stem workflow. Be careful if you plan label releases or need bulletproof provenance: the Warner-era terms replaced ownership with commercial rights, download caps are landing on paid tiers, and pre-licensing models will be deprecated. For legally cleaner commercial background music, ElevenLabs Music is the safer alternative; for pure instrumental fidelity, Udio still sounds better but cannot export anything today.

### Stable Audio

> The only major AI music generator trained on 1.28M fully licensed recordings, open weights included, from $11.99/month

Strengths:
- Trained on 1,278,902 fully licensed recordings with full attribution published, backed by UMG and Warner deals: the lowest legal-risk option in the category
- Stable Audio 3.0 (released 2026-05-20) generates structured tracks up to 6 min 20 s, more than double the 2024 version, via a new semantic-acoustic autoencoder
- Three of the four 3.0 models are open-weight on Hugging Face (Small SFX and Small at 459M, Medium at 1.4B), free to use commercially under the Community License below $1M annual revenue
- Stable Audio 2.5 renders up to 3 minutes of audio in under 2 seconds on a GPU, with audio inpainting to extend your own uploads

Weaknesses:
- Instrumental music and SFX only: no vocals, no lyrics, no complete songs, unlike Suno or Udio
- Free plan is non-commercial and capped at 20 tracks/month, and free-tier audio uploads are cropped to 30 seconds (6 minutes for subscribers)
- Mixed user feedback on musical quality: solid for background beds and ambience, below Suno's latest models for polished full compositions

Verdict: Pick Stable Audio if legal safety is your top criterion: it is the only major generator with a fully licensed, fully attributed dataset plus open weights, and the $11.99 Pro plan covers most video and podcast workflows. Developers should try the open-weight Medium model on Hugging Face before paying anyone. Skip it if you need vocals or complete songs: Suno does that and Stable Audio does not sing a note. For high-volume, editable background tracks, Soundraw's unlimited plan is the simpler buy.
