What did discovery actually find?

For most of the case, the question was scale: how much copyrighted music did Suno feed its model? Now there is a number, or at least a floor. Using Audible Magic, the industry standard fingerprinting tool, experts got physical access to Suno's training data on November 3, 2025, finished the analysis by January 2, 2026, and delivered the matches days later. The verdict was blunt: millions of the plaintiffs' recordings. Suno had already conceded the shape of it in its own answer, admitting the model was trained on tens of millions of recordings that presumably included works owned by the labels.

On May 21, 2026, Universal and Sony moved to add 61,026 specific recordings to a complaint that started, in June 2024, with just 560. They called that haul only a small fraction of what discovery turned up.

Why does a July ruling matter beyond the majors?

The Massachusetts case reaches a summary judgment hearing in July before Chief Judge F. Dennis Saylor IV, and Suno is betting everything on fair use. A ruling either way lands on every producer and label that has ever worried about a catalogue being swallowed by a model. If fair use loses, the licensing template set by earlier deals, fractions of a cent per generation, becomes the floor for doing business. If it wins, training on copyrighted music without asking becomes a lot harder to challenge.

Suno says it is entitled to an expeditious resolution of its fair use defense. The labels say denying them would reward copying on an unprecedented scale and then hiding it.

Where do the majors stand now?

The front has split. Warner settled in November 2025, struck the first licensing deal of its kind with an AI music generator, and was dismissed from the case in January 2026. Universal and Sony did not settle; their talks with Suno reportedly stalled, and they are pressing on. None of it has slowed the company: Suno raised 400 million dollars in June 2026 at a 5.4 billion dollar valuation, money that buys a lot of legal patience while the rest of the business waits to see what the summer ruling makes legal.
