Sony Music Files New Lawsuit Against Udio After Court Rejects Adding 30,117 Recordings to Earlier Case

Sony Music Entertainment filed a new lawsuit against AI music generator Udio in a New York court on Monday. The complaint accuses the company of infringing copyrights on 30,117 Sony recordings. Sony identified the works through audio fingerprinting after gaining access to Udio’s training data during discovery in the 2024 case.

The company stated that the list represents only a small portion of the works Udio infringed. Sony accused Udio of obtaining the recordings by ripping audio from YouTube. A court on June 29 rejected Sony’s request to add the 30,117 works to the original complaint.

That case remains limited to 333 works. The court affirmed plaintiffs’ rights to pursue damages for all infringed copyrights. Universal Music Group and Warner Music Group joined the 2024 suit but later reached licensing deals with Udio.

Sony is the only major label that has not settled. Udio admitted using audio data from YouTube to train its models but asserted that the practice amounts to fair use. Sony requests a jury trial, an injunction blocking further infringement, and statutory damages of up to $150,000 per infringed work.

The full list of recordings appears in the court filing.
