What to know

  • Sony Music and UMG argue Suno's new v6 models—trained in partnership with Warner Music Group and BMG—still infringe copyright by using outputs and preference signals from earlier unlicensed models, treating them as 'fruit of the poisoned tree.'
  • The labels claim Suno is liable for infringing at least 60,202 sound recordings, with potential damages up to $9 billion plus per-violation penalties for circumventing YouTube's anti-downloading tools.
  • Suno denies the allegations, stating v6 models are trained on licensed content and community interactions, and that the legal claims are 'fundamentally flawed.'
  • This is the second lawsuit against Suno; it builds on a previous joint suit by Sony, UMG, and Warner, and follows a July 2026 hack revealing Suno had scraped millions of songs from YouTube Music, Deezer, and Genius.

“We are excited for a future where AI and the music industry continue to strengthen one another and build entirely new product experiences for artists, fans and the broader music community.”
