Suno has asked a court to compel the MLC to comply with a subpoena for documents, in a motion filed in the week before 22 October. Udio's owner, Uncharted Labs, sent the MLC a near-identical subpoena, which the MLC itself calls "substantially identical", and that one has drawn its own motion to compel.
The data at issue is monthly, label-by-label performance information from 2021 to today. Suno's first subpoena, in April, named eleven services, among them Spotify, YouTube, Apple, Amazon and TikTok. A narrower version in August dropped Meta, Snapchat and TikTok, leaving eight. For each track the records would show the ISRC code, title, label, distributor, play count, type of use, match status and featured artists.
The two AI companies say the numbers go to the heart of the major labels' case: whether AI-generated music has cut the majors' share of streaming and the royalties they earn. They also refuse to confine the request to the labels that are plaintiffs, arguing that would defeat the point. Their shared lawyer, Chris Campbell of The Campbell Firm, says the sides spent close to four months trying to narrow the request, with Suno even offering to cover the MLC's costs. A letter he sent to the MLC's lawyers at Pryor Cashman, dated 23 September, set out that history, and he argues that a limit to the plaintiff labels "would defeat a central purpose of the request".
The MLC objects that the request is vague and overbroad. It says it does not collect this data from labels or distributors, has no required label fields, and that streaming services have objected to disclosure. Suno's side says the MLC first agreed to supply several terabytes for about $5,000, then reversed course.
About Suno
Suno has been in court with the major labels since June 2024, when Universal, Sony and Warner Music Group sued it, along with Udio, over how their systems were trained on recordings. Warner was the first to leave. In late November 2025 it settled and announced a partnership with Suno.
Under that deal Suno was to take over Songkick, Warner's concert-discovery platform, and to release a new licensed model in 2026 while retiring the current one. Warner and Universal had settled with Udio in the weeks before. Universal and Sony stayed in the case against Suno.

The fights over non-party subpoenas are growing as the majors' suits against Suno and Udio continue; Sony is still in litigation with Udio. The filings carry the case numbers 1:24-cv-11611, 3:26-mc-00020 and 3:26-mc-00021. What the court decides could shape how much market evidence AI companies can pull from outside parties in these suits. On Udio's subpoena, a joint schedule has the MLC responding by 30 October and Udio replying by 13 November.
