Jamendo filed a notice of voluntary dismissal against Suno in the US District Court for the District of Massachusetts on Thursday, August 13, ending a copyright infringement case it had brought only six weeks earlier. The dismissal is without prejudice, meaning Jamendo remains free to sue again later. Neither the filing nor either company gave a reason for the withdrawal, and nothing in the notice points to a settlement between the two sides.
Jamendo, a subsidiary of Winamp Group, sued Suno on June 29 and filed an amended complaint in late July before dropping the case. The suit centered on the MTG-Jamendo Dataset, a collection of more than 55,000 tracks Jamendo released around 2019 for non-commercial research, on the condition that any company training a commercial AI system on it buy a license. Winamp Group CEO Alexandre Saboundjian had framed the original filing as part of an effort to protect artists' rights as AI reshapes the industry, saying "innovation and respect for intellectual property must go hand in hand."
The withdrawal doesn't end Jamendo's legal activity around that same dataset. The company sued chipmaker Nvidia a week before it went after Suno, accusing it of training two AI audio models on the same tracks, and that California case remains open, alongside a related commercial claim worth roughly 16 million euros pending in a Belgian court. A second lawsuit against Suno, brought by Poseidon Wave Media on behalf of the instrumental duo the American Dollar, was also dropped around the same time, but with prejudice, closing it for good.
Universal Music Group and Sony Music are still pressing their own case against Suno in the same Massachusetts court, in the action the RIAA filed in 2024, and are now trying to add more than 61,000 recordings to it, a motion Suno is opposing. Fact discovery in that case closes September 30, with dispositive motions due the following April.
The dismissal lands in the middle of a broader shift in how Suno is trying to make peace with rights holders. CEO Mikey Shulman said on August 6 that the company would begin using audio watermarking and fingerprinting technology "in the coming weeks" so its songs can be identified once they leave the platform, alongside a tighter download policy meant to curb mass distribution. Days later, Suno struck a global licensing deal with BMG covering both recorded music and publishing.
The company's legal record stays mixed even so: it lost a first-instance copyright ruling in Munich on July 31 brought by Germany's collecting society GEMA, and still faces a claim from Denmark's Koda, a US class action from independent artists, and a separate class action over a breach of its own user data. Suno raised more than $400 million in a Series D round in June that valued the company at $5.4 billion.
