Sony Music Entertainment has filed another lawsuit against Udio, accusing the AI music generator of infringing the copyright of more than 30,000 of its songs, ranging from Elvis Presley’s Hound Dog to Beyoncé’s Say My Name, and Harry Styles’ As It Was. The lawsuit, filed in a New York court on Monday, claims that this list represents “only a small portion of Plaintiffs’ works that Udio infringed,” as reported earlier by Music Business Worldwide. In 2024, Sony, along with Universal Music Group and Warner Records, filed a lawsuit against Udio and the AI music-maker Suno. After gaining access to Udio’s training data through discovery, Sony claims it identified additional songs using an “audio fingerprinting” technique.

Sony has now made the more than 30,000 songs the subject of its new lawsuit, which the company says it could expand. It claims Udio “admitted that its generative AI models were ‘constructed by showing the program a vast amount of different kinds of sound recordings,’” including from YouTube. UMG and Warner Music Group have since settled with Udio and are now partnering with the company as the music industry embraces AI.
