UMG and Sony file another copyright lawsuit against Suno, and the AI company claps back with a statement that the suit is “fundamentally flawed.”

Universal Music Group and Sony Music Entertainment continue to heat things up in their ongoing legal battle against the AI music platform Suno. The majors have filed another copyright lawsuit against the company over its controversial latest AI model that the labels allege was still trained on unauthorized IP. But Suno says the claims “remain fundamentally flawed on both the facts and the law.”

According to the complaint, filed in the U.S. District Court for the District of Massachusetts, Suno allegedly copied 60,202 sound recordings owned by the majors and used them without permission to develop its AI-powered music generation tech. But the labels claim that Suno even trained its new v6 model using accumulated knowledge from earlier models—even though Suno asserts that the new model was trained on authorized recordings per its recently acquired licensing deals.

Suno was quick to challenge those claims with a statement sent to Digital Music News:

“These claims remain fundamentally flawed on both the facts and the law. What remains unchanged is that Suno exists so that more people can make new music. Every song on Suno begins with a person and an idea. When someone asks for a particular artist, we translate that into the musical qualities behind the request—not so that a user can imitate someone else’s work, but so that people learn the language of music and make something of their own.”

“Over the past two years, we have doubled down on this goal, launching v6 in partnership with WMG, BMG, and Believe. v6 was trained on content licensed from our partners, interactions including creations and preference signals from our community, and the accumulated learnings from our team. We are excited for a future where AI and the music industry continue to strengthen one another and build entirely new product experiences for artists, fans, and the broader music community.”

Meanwhile, longtime Suno subscribers are also dissatisfied with the platform’s latest model, claiming that the output is inferior to that of the previous versions.
