Universal Music Group and Sony Music amended their lawsuit against Suno, accusing the AI music company of using 'stream ripping' to bypass YouTube's encryption and train its AI. Judge F. Dennis Saylor IV allowed the claim under the Digital Millennium Copyright Act but denied adding 61,026 recordings to the existing 560. The case focuses on whether Suno's use of copyrighted material constitutes fair use.
