Universal Music Group and Sony Music have opened a new legal front in their fight with Suno, and this time the target is the distributor in the middle. In a filing lodged on Wednesday, October 14, 2026 in Manhattan federal court, the two majors asked a judge to force DistroKid to comply with a subpoena for internal data on how many AI-generated songs it delivers to streaming services each month, Billboard first reported.
What the labels want
The subpoena went out in September. According to the labels, DistroKid “refuses to produce a single document.” UMG and Sony want monthly figures on AI-generated submissions, plus the results of the AI-detection tool DistroKid uses to screen uploads. Digital Music News reported that the filing also claims DistroKid distributed nearly 12 million tracks to a single unnamed streaming service between March and September 2026, more than all other distributors combined.
The labels describe DistroKid as “one of the primary conduits by which the streaming market is being flooded with AI-generated recordings.” Their argument is that Suno “does not track where its outputs are distributed once they leave Suno’s platform,” while DistroKid sits upstream of the streaming services. “That makes DistroKid a singular source of relevant evidence,” the filing says. “The question of how much AI-generated music is reaching digital platforms, and what it is earning there, is not information that is available from Suno.”
Why a distributor matters to a fair use case
UMG and Sony have been suing Suno since 2024, alleging it copied recordings without permission to train its song generator. Suno disputes that and argues its use is protected by fair use. One factor courts weigh in fair use is the effect of a use on the market for the original works, and that is where the labels say DistroKid’s numbers come in. “Suno’s industrial-scale theft will lead to a market flooded with machine-generated recordings that compete with human-created works,” their attorneys wrote. “DistroKid’s AI-detection results are direct evidence of that flood.”
DistroKid has resisted on the grounds that the data has nothing to do with how Suno built its models, according to the filing as described by Billboard and Law Commentary. Law Commentary also noted a limit to the labels’ theory: a raw count of AI uploads would not by itself show those tracks came from Suno, or that Suno caused any particular loss.
In a statement to Billboard on October 16, a DistroKid spokesperson said: “DistroKid is a third party in the ongoing litigation between Universal Music Group, Sony Music and Suno. We are committed to transparency and will continue to cooperate with the legal process as this matter proceeds.” Suno did not immediately respond to Billboard.
Two fights, one distributor
The new action sits alongside a separate lawsuit Universal filed against DistroKid in September, which accuses the distributor of letting bad actors upload what UMG calls “AI-generated slop” at scale. Sony is not a party to that case. DistroKid has denied wrongdoing there but acknowledged removing some uploads after it was filed, and some independent musicians have objected that legitimate releases were taken down. As of October 16, no ruling had been issued on the new request to compel. For independent artists who rely on DistroKid, the outcome could reveal for the first time how much machine-made music is competing for the same streaming royalty pool.
