Here are the 30,000 songs Sony is suing Udio's AI music generator over

Sony Music Entertainment just escalated its legal war against AI music startup Udio, and the details are striking. According to The Verge, the company filed an updated lawsuit in New York naming more than 30,000 specific songs it claims Udio scraped without permission, including Elvis Presley's Hound Dog, Beyoncé's Say My Name, and Harry Styles' As It Was. Sony says this list represents only a fraction of the infringement.

This lawsuit builds on the joint action Sony filed alongside Universal Music Group and Warner Records in 2024 against both Udio and rival AI music generator Suno. The key development here is that Sony gained access to Udio's actual training data through legal discovery, which means they now have receipts. That's a huge shift from the earlier lawsuit, which relied more on circumstantial evidence and output analysis.

The scale of 30,000 songs is significant because it shows the music industry isn't bluffing about the scope of what they consider unauthorized use. If Sony can prove Udio ingested and learned from these recordings without licensing them, the statutory damages alone could be astronomical. We're talking potential liability in the billions, not millions.

What makes this case particularly important for anyone watching AI development is that it could set precedent for how training data is treated legally. The music industry has more unified copyright infrastructure than almost any other creative field, which makes it the perfect testing ground for these questions. Whatever happens here will ripple out to image generators, video tools, and text models.

For AI music tools to survive, they'll likely need to either prove fair use, which is an uphill battle when you're directly competing with the original works, or build licensing deals with rights holders. Some startups are already taking the licensing route, but it's expensive and complicated.

What this means for you: if you're using AI music generators for commercial projects, now is the time to read the fine print on their terms of service and understand your liability. Many tools don't indemnify users against copyright claims. For safer AI-assisted music work, try this prompt with a text-based AI: "Generate original chord progressions and song structures in the style of [genre], but write out the music theory so I can perform it myself or hire musicians." That keeps the creative AI assistance while you maintain full ownership of the actual recording.
