Jamendo sues Suno again, alleging AI training used its production music catalog and metadata without permission

A production music company, Jamendo, has filed another copyright lawsuit against the AI music service Suno, according to reporting by Billboard. The suit renews a key question for the fast-growing generative-music industry, whether AI systems can use existing music catalogs and related information to train models without obtaining rights-holder permission.

Billboard reports that Jamendo’s complaint makes similar allegations to claims Jamendo brought against Nvidia last week. In both cases, the core contention is that unlicensed use of Jamendo’s catalog and metadata occurred during the training of AI systems and that such use infringes copyright and related protections.

The dispute also highlights how catalog data can become part of the litigation record. Jamendo’s allegations, as described by Billboard, focus not only on the underlying music works but also on metadata, a component used to organize, identify, and connect musical content for rights management, search, and distribution. Rights holders and platforms have increasingly disagreed about whether metadata is treated as protectable content and whether training workflows can treat it as freely usable.

Suno, an AI system that generates music from text prompts, has faced mounting scrutiny as courts and rightsholder groups test the boundaries of copyright law in the context of machine learning. While the lawsuit’s details and legal theories will ultimately be handled through the court process, Billboard’s reporting frames Jamendo’s action as part of a wider effort to address alleged unauthorized learning and resulting outputs.

The new filing comes as the music industry continues to debate licensing models for AI-generated content. For public-facing platforms, unresolved questions about training permissions affect compliance decisions, contractual negotiations with rights holders, and the risk profile for deploying generative features at scale.

If Jamendo’s claims proceed, the case could require the parties to address key issues that recur in AI copyright litigation, including how courts evaluate the relationship between training data and copyrighted works, and what evidentiary showing is required to link alleged copying to the training process.

In the near term, the next steps will likely include court filings related to jurisdiction and pleading requirements, followed by discovery. The pace of those proceedings will determine when any substantive rulings or settlement discussions occur, and whether other rights holders continue to file similar actions or seek consolidated handling of comparable claims.
