TL;DR: Suno launched its v6 AI music model with actual record label partners this time, Warner, BMG, and Believe all signed on. Universal and Sony, who are not partners, immediately sued anyway, claiming v6 is built on the same stolen training data as the earlier models they already had in court.
For a while it looked like Suno might be settling into something resembling peace with the music industry. The company’s v6 model shipped with a genuinely different story attached to it: real licensing deals, real revenue sharing, actual label names willing to put their catalogs behind an AI music generator instead of suing over one. Warner Music, BMG, and independent distributor Believe all signed on as partners for v6, a meaningful shift from Suno’s earlier posture of training first and negotiating never.
Universal Music Group and Sony Music were not invited to that party, and they responded the way you’d expect. The two labels filed a new lawsuit against Suno specifically targeting v6, arguing the model isn’t actually clean. Their claim, described in court filings as the model being “the fruit of the same poisoned tree,” is that v6 was built on top of earlier Suno models that Universal and Sony already allege were trained on unlicensed copyrighted recordings, roughly 60,202 of them by their count in this latest filing.
If that holds up, it’s a serious problem for Suno’s rehabilitation story. You can’t fully launder a model’s origins just by layering new, properly licensed training on top of an older model that was built on stolen data in the first place, at least according to the labels suing over it. The underlying architecture and whatever it learned from those earlier training runs doesn’t just disappear because new, cleaner data got added later. Suno disputes this characterization, unsurprisingly, and has pointed to its licensing deals as evidence the company is operating in good faith going forward.
What makes this case interesting beyond the usual AI copyright drama is the split it reveals inside the music industry itself. Warner, BMG, and Believe looked at the same underlying legal exposure Universal and Sony are suing over and decided a negotiated deal was the smarter play. Universal and Sony looked at the exact same situation and decided to keep fighting in court. Both bets are reasonable. Licensing early gets you a seat at the table and some revenue now, while a lawsuit, if it succeeds, could extract a much bigger settlement or force structural changes to how Suno operates going forward.
Suno isn’t the only AI music company fighting this exact battle. ElevenLabs and others have faced similar claims, and the broader pattern across generative AI, text, image, now music, is the same: companies train first, apologize or license later, and courts are slowly being asked to decide whether that sequence is legally acceptable after the fact. Music adds a wrinkle the others don’t have in quite the same way, since labels control exclusive rights to specific recordings in a way book publishers and stock photo agencies generally don’t.

Bottom Line: Licensing deals don’t automatically wash away old legal exposure, and Universal and Sony just made that argument in writing. Every AI company sitting on data it didn’t fully license should be paying attention to how this plays out, because “we fixed it going forward” might not be the defense they’re hoping it is.
