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

Sony Music has filed a detailed list identifying roughly 30,000 songs it says are at the heart of its copyright lawsuit against Udio, the artificial intelligence company behind a popular AI music generation tool. The filing lays out, track by track, the scope of material the label claims Udio pulled into its systems without authorization.

According to the label, Udio "copied and ingested" recordings from Sony's catalog, using them to build and train the models that power its song-generating service. The newly submitted list functions as evidence meant to quantify the scale of the alleged infringement, moving the dispute from broad accusations to a concrete, numbered inventory of works Sony says were used without a license or payment.

The case sits within a much larger legal confrontation between the recorded-music industry and AI startups. Major labels, including Sony, began suing Udio and a rival service, Suno, in 2024, arguing that both companies built their AI tools by feeding enormous volumes of copyrighted recordings into machine-learning systems, then let users generate new songs that echo the style, structure, and sound of existing hits. Labels have argued this amounts to industrial-scale copying disguised as innovation.

Publishing a song-by-song list changes the character of that fight. Rather than arguing in the abstract about "massive" infringement, Sony is now asking courts to weigh a specific, enumerable body of work, which could make it easier to calculate potential damages and harder for Udio to dispute the extent of what was allegedly used.

AI music companies have generally defended their approach by arguing that training a model on existing recordings is a transformative process protected under fair-use principles, since the output is new material rather than a direct copy of any single song. That legal theory remains untested at scale in the music industry, and courts weighing similar claims against AI companies in other creative fields, including publishing, journalism, and visual art, have so far reached mixed conclusions.

The stakes extend beyond the companies named in the suit. Songwriters and performers whose recordings may appear on Sony's list have a direct financial interest in the outcome, since a ruling against Udio could force AI developers to negotiate licensing deals before training on copyrighted audio, while a ruling in Udio's favor could validate the practice of scraping commercial catalogs without artist consent.

The dispute also lands amid a broader reassessment of how the entertainment industry engages with generative AI tools, with some labels simultaneously pursuing litigation against certain companies while exploring licensing partnerships with others, reflecting uncertainty over whether AI music generators are a threat to be blocked or a market to be monetized.

No final ruling has been reached, and the case is expected to proceed through further discovery and motions before any judgment on whether Udio's use of Sony's catalog was unlawful. The outcome is likely to influence how other AI music platforms approach training data going forward.
