Sony Music and Universal go to court against Suno: "Dragging a new model on the releases of a counterfeit model is laundering counterfeiting"

The two majors filed a new complaint in Massachusetts on September 19, targeting the Suno v6 model family and listing 60,202 protected registrations.

Sony Music Entertainment and Universal Music Group filed a new lawsuit against Suno in federal court for the District of Massachusetts on September 19, 2026. The two majors argue that the v6 family of models, presented by the company as based on agreements with labels, remains built on a technology whose initial training was illegal. Their formula sums up the argument: training a "new" model on the productions of a counterfeit model does not erase the counterfeit, it clears it.

The complaint lists 60,202 protected recordings that have been exploited since the launch of the service, and claims a declaration of infringement, legal damages and reimbursement of legal fees, without publicly quantifying the amount targeted.

The case extends an initial lawsuit filed in June 2024 by the same two record labels accompanied by Warner Music Group. In the meantime, Warner, BMG and Believe have signed licensing agreements that precisely power the v6 models. Suno rejects the move, saying that v6 only uses licensed content and productions from its user community, and calls the complaint factually and legally wrong.
