Sony Music Entertainment has filed a fresh lawsuit against AI music generator Udio, accusing it of unlawfully copying more than 30,000 songs by artists including Beyoncé, Harry Styles and Elvis Presley to train its models. The new complaint, lodged on 20 July 2026 in New York, follows a judge's refusal to let Sony add the newly discovered tracks to its original 2024 suit, prompting the label to launch a separate case instead. It forms part of a wider legal battle between major record labels and AI music firms over how copyrighted recordings can be used to train generative models.

Sony's original action against Udio and rival Suno was brought jointly with Universal Music Group and Warner Music Group in June 2024, but Universal and Warner have since settled and struck licensing deals with Udio, which is preparing an industry-backed model for release later this year. Sony alleges discovery revealed 30,117 of its tracks in Udio's training data, taken from YouTube without permission; Udio has argued such use constitutes fair use. Sony is seeking at least $150,000 per infringed work and a court order blocking Udio from using its catalogue to train future models.
