Universal Music and Sony want to know how many AI-generated songs DistroKid has released.

The companies filed a new filing this week, arguing that the information is crucial to the labels' lawsuit against Suno.

Universal Music Group and Sony Music are seeking to require independent music distribution platform DistroKid to disclose the number of AI-produced songs the service uploads per month, claiming they need the information in a lawsuit filed by record majors against AI music production platform Suno.

In a new filing filed in federal court earlier this week, UMG and Sony announced that they have served subpoenas against DistroKid seeking the company's monthly recording submissions and its AI detection tools. DistroKid declined to share any documents, the companies said, with Sony and UMG calling the data "highly relevant information available only to DistroKid and relevant to a case where the market impact of AI-generated music is a central question."

A representative for DistroKid did not immediately respond to a request for comment.

Notably, the new action comes about a month after UMG sued DistroKid in September, alleging that the company helped bad actors upload AI songs on a massive scale, undermining royalties for real artists. Sony Music is not a party to the UMG DistroKid lawsuit.

Regarding UMG's lawsuit, DistroKid previously told Billboard that "we take copyright protection, fraud prevention, and the integrity of the music ecosystem seriously, and we work closely with digital streaming platforms, rights holders, and other industry partners in these efforts."

We strongly disagree with UMG's claims and are disappointed that DistroKid chose to litigate rather than develop industry processes to address these issues, DistroKid said at the time.

UMG and Sony's latest filing also says that DistroKid "plays a major role in the distribution of AI-generated music on digital services." The company called the scale of DistroKid's releases "astonishing," stating that between March and September 2026, "DistroKid distributed nearly 12 million songs to a major digital service, comprising more than half of all songs submitted to that service and more than all other distributors delivered."
