Suno is a U.S. company that develops an AI music generator producing songs from text prompts. It is a defendant in UMG Recordings v. Suno (AI music training data), the copyright suit brought by major record labels coordinated through the RIAA in the U.S. District Court for the District of Massachusetts (No. 1:24-cv-11611, filed June 24, 2024), which alleges its models were trained on copyrighted recordings (Source: courtlistener.com). Suno raised a $400 million Series D at a $5.4 billion valuation in June 2026 while the litigation continued (Source: techcrunch.com).
Training-data disclosure (July 2026 hack)
On July 15, 2026, hacked Suno source code became public showing that the company scraped YouTube Music (113,879 hours; over 2 million clips), Deezer, Genius, Pond5, Jamendo, IMSLP, and roughly 1 million hours of podcasts for training data. The hacker also accessed customer and Stripe payment data, and Suno confirmed a "limited security incident" dating to November 2025. 404 Media reported that the data corroborates the RIAA's stream-ripping allegations in its ongoing litigation against the company (Source: 404media.co).
Have I Been Pwned reported on July 21, 2026 that the November 2025 breach exposed personal information on more than 55.3 million people — names, addresses, phone numbers, purchases, and partial payment-card numbers drawn from Suno's Stripe account — alongside the source code. Suno had not publicly disclosed the breach or notified users as of that reporting; spokesperson Rachel Racusen confirmed the incident and did not dispute the user count (Source: techcrunch.com).
Suno did not notify affected users of the breach, stating that individual notices were not required under applicable privacy laws (Source: techcrunch.com).
German litigation
On July 31, 2026 the Regional Court of Munich ruled that Suno lacked the right to process songs by artists represented by GEMA, Germany's state-mandated licensing agency, and ordered the company to disclose revenue derived from the infringement; damages were not quantified and the verdict is appealable (GEMA v. Suno (Munich Regional Court)). GEMA had sued over Suno's use of freely available music on YouTube by artists including Alphaville. GEMA chief executive Tobias Holzmueller called it "a verdict of global significance"; Suno said it disagreed and would evaluate all options, including appeal (Source: reuters.com). More than 1,800 artists support the parallel U.S. class actions against Suno and Udio.
Artist identity-rights litigation
A separate line of claim opened on August 31, 2026, when Jason Isbell, David Lowery, Guy Forsyth and Eduardo Calle sued Suno in federal court seeking class-action status, alleging the company "built and trained a model to index musicians by name" so that entering an artist's name generates a channel, song, description and graphic invoking that identity. The theory rests on performers' identity rights rather than copyright, distinguishing it from the pending claims by Universal Music Group, Sony Music Group and Round Hill Music. Warner Music Group settled its own suit and entered a partnership with Suno in late 2025. Suno said the claims are "without merit," that it blocks prompts for specific artists' names and copyrighted songs, and that it screens uploaded audio and lyrics through third-party providers (Isbell v. Suno (right of publicity); Source: hollywoodreporter.com; wsj.com).
Distribution of Suno outputs
Suno is not a party to UMG Recordings v. DistroKid, filed September 15, 2026, but the complaint alleges that "technical analysis" shows over 97% of the tracks released by the DistroKid account "Chill Flow Radio" (1,901 tracks in twelve months) and over 98% of those released by "Mellow Vibes Radio" (1,615 tracks) "are raw outputs from the AI song generator, Suno" (Complaint, UMG Recordings v. DistroKid (D. Del., 2026)). Music Business Worldwide, reporting the suit, cited SIQA figures that 90.4% of 1,551 AI music tracks submitted to SIQA's charts in the first quarter of 2026 were made with Suno and 75.8% were distributed by DistroKid (Source: musicbusinessworldwide.com).
