Sony Music Entertainment has filed a new copyright lawsuit against AI music generator Udio, alleging infringement on more than 30,000 songs including works by Beyoncé, Britney Spears, Johnny Cash, and Harry Styles in a New York court filing. The aggressive action marks a significant escalation, particularly notable because Sony's former co-plaintiffs Universal Music Group and Warner Music Group have already settled their disputes with Udio, revealing deep strategic divisions among the major record labels.

The lawsuit represents Sony's continuation of its combative stance towards AI music tools, building on its original 2024 legal action that initially targeted both Udio and competitor Suno. While Universal and Warner have pursued negotiated licensing agreements with these AI firms, Sony's decision to pursue independent litigation underscores the fragmentation within the music industry over whether courtroom battles or commercial arrangements offer the more effective path to protecting artist rights amid rapid AI advancement.
