What is Google Flow Music?
Google's full-song AI music platform, born as Riffusion, rebranded ProducerAI in 2025, acquired by Google in February 2026 and relaunched as Flow Music in April 2026 inside Google Labs. It generates vocals-included tracks up to 3 minutes with DeepMind's Lyria 3 Pro model (structured intros, verses, choruses), plus conversational Replace and Extend remixing, stem separation and Veo-powered music videos. Every track carries an inaudible SynthID watermark.
Google Flow Music pros & cons
Pros
- Aggressive pricing: free tier gives daily top-up credits (roughly 20 songs a day per HN users), and Starter at $8/month includes 3,000 credits (~600 songs), undercutting Suno Pro ($10 for ~500 songs)
- Lyria 3 Pro (DeepMind, March 2026) generates structured full songs up to 3 minutes, with promptable intros, verses, choruses and bridges
- Conversational editing is a genuine differentiator: Replace and Extend let you say things like turn the bridge into a dubstep drop and it edits just that section
- Stem downloads (vocals, drums, instruments) and MP3, WAV, M4A export included across plans
- Music video generation via Google's Veo model, something neither Suno nor Udio bundles
- Google does not claim ownership of generated content, and the Believe/TuneCore partnership (May 2026) signals a path to legitimate distribution
Cons
- Output quality trails Suno and Udio: the HN consensus is that it ignores many prompt instructions, adds unrequested instruments and produces generic results (one musician called some vocals Casio toy keyboard level)
- Every track is watermarked with SynthID, with no opt-out, and platforms can detect it
- Independent musicians sued Google in March 2026 alleging Lyria 3 was trained on copyrighted YouTube recordings, an unresolved legal risk for commercial users
- Google Labs experimental status: users openly advise saving your collection before shutdown given Google's product graveyard
- 3-minute cap per track (Suno does 8+ minutes) and mandatory age verification annoys users
The arena’s verdict
Take Google Flow Music if volume and price matter more than polish: the free tier alone (about 20 songs a day) covers most hobbyists, and $8/month for roughly 600 songs with stems, publishing and video generation is the best raw deal in AI music right now. Skip it if you need best-in-class quality or fine prompt control, Suno v5.5 still wins clearly there for $10/month, and Udio remains stronger on fidelity. Commercial users should also weigh two real risks before building on it: the unresolved March 2026 training-data lawsuit and Google's habit of killing Labs experiments.

What the crowd says
“Asked for solo banjo, got a full band. Asked again, got banjo plus drums. Prompt adherence is way behind Suno, and the SynthID watermark means every platform knows it's AI.”
“The Replace feature is the killer bit. Told it to turn my chorus into a synthwave breakdown and it edited just that section. Nothing else does this.”
“20 free songs a day is stupidly generous. I cancelled my Suno sub for background stuff and only miss it for long tracks.”
