Sony Music files a second copyright lawsuit against Udio

Sony Music and several affiliated labels filed a second federal copyright complaint against Udio on 20 July in the Southern District of New York.

The new case follows a procedural limit in the earlier lawsuit: a judge did not allow Sony to add another large group of recordings there. Sony alleges that the second complaint concerns 30,117 sound recordings. That number is a plaintiff's claim, not a court finding.

Why a second case matters

The filing keeps the central dispute intact: whether training and output behavior involved unauthorized copying of label recordings. Splitting the claims across two cases may affect procedure and discovery, but it does not resolve the underlying copyright questions.

Udio will have an opportunity to answer the allegations. Until the court reaches the merits or the parties settle, the docket proves that a complaint was filed — not that infringement has been established.
