Jamendo Drops Copyright Lawsuit Against Suno After Six Weeks, Leaving Door Open to Refile

Jamendo has dropped its copyright infringement lawsuit against AI music platform Suno, six weeks after filing it and without explanation.

The subsidiary of the Winamp Group filed a notice of voluntary dismissal on August 13 in the US District Court for the District of Massachusetts, according to Music Business Worldwide. The dismissal was signed by Jamendo attorney Alexander T. Hornat and filed under a federal rule that lets a plaintiff withdraw a case unilaterally before the defendant has formally responded. Suno had not yet served an answer or a motion for summary judgment.

The notice set out no reason for the withdrawal and made no mention of a settlement. Crucially, the case was dismissed without prejudice, meaning Jamendo is free to bring the same claims against Suno again.

Jamendo sued Suno on June 29, accusing the AI music company of building its platform on Jamendo's catalog and data without authorization. The complaint centred on the MTG-Jamendo Dataset, a collection of more than 55,000 tracks drawn from Jamendo's catalog and dating back to around 2019. Jamendo had released the dataset for non-commercial research and required companies training commercial AI systems on it to purchase a license. Jamendo filed an amended complaint in late July, weeks before pulling the case entirely.

The withdrawal leaves Suno with one fewer legal opponent, but the AI music company is not out of the woods. Universal Music Group and Sony Music Entertainment continue to sue Suno in the same Massachusetts district, in an action brought by the RIAA, the US recorded-music trade body, in June 2024.

A separate lawsuit against Suno, filed by Poseidon Wave Media — the entity behind the instrumental duo The American Dollar — was dismissed with prejudice in May, meaning it cannot be refiled. That suit had claimed the duo's licensing revenue had been nearly eliminated since Suno launched.

Jamendo, for its part, still has an active front against another defendant. The company sued chipmaker Nvidia on June 22, a week before its Suno filing, over the alleged use of the same MTG-Jamendo Dataset to train two of Nvidia's AI audio models. That case, filed in the US District Court for the Northern District of California, has not been withdrawn. A related commercial claim of roughly EUR 16 million (approximately USD 18.2 million) against Nvidia Technologies Belgium is also pending in Belgium's Ghent Enterprise Court.

Winamp Group CEO Alexandre Saboundjian has not publicly commented on the Suno dismissal.

What makes the withdrawal notable is the timing. Jamendo amended its complaint against Suno just weeks before walking away, suggesting the legal strategy shifted quickly — though without a stated reason, settlement discussions, a shift in evidence, or simply a tactical regrouping are all possible explanations. The "without prejudice" designation keeps every option open, and in litigation, that often means the plaintiff intends to come back.
