UMG Recordings, Inc. v. Suno, Inc. is a copyright infringement lawsuit filed by major record labels against AI music generation company Suno, alleging that Suno trained its AI models on vast quantities of copyrighted sound recordings without authorization.

Allegations

The plaintiffs — including Universal Music Group, Sony Music Entertainment, and other major labels — allege that Suno copied millions of copyrighted sound recordings to train its AI music generation models. The labels argue this constitutes mass copyright infringement on an unprecedented scale.

The August 25 amended complaint alleges that Suno used YT-DL and YT-DLP to bypass YouTube’s “rolling cipher” and obtain recordings for its training data.[5][6]

Settlement Status

Warner Music Group and Suno announced a licensing partnership on November 25, 2025. Warner’s announcement states that the agreement also settles the companies’ previous litigation.[7]

Procedural History

  • June 24, 2024 — Complaint filed in District of Massachusetts
  • 2025 — Discovery and motion practice
  • November 25, 2025 — Warner Music Group announces a partnership with Suno settling their litigation.[7]
  • August 18, 2026 — Judge F. Dennis Saylor IV permits UMG and Sony to add a DMCA Section 1201 stream-ripping claim but denies their request to add 61,026 recordings.[6]
  • August 25, 2026 — UMG and Sony file the amended complaint.[5]

Significance

This case is one of the most important AI copyright disputes in the music industry, alongside the parallel case against Udio. The outcome will help define whether AI training on copyrighted music constitutes fair use and establish licensing frameworks for AI-generated music.

Separate September 2026 action

Universal and Sony plaintiffs filed a second Suno action, No. 1:26-cv-14275, on September 18, 2026, asserting claims concerning 60,202 recordings.[8]
