Nvidia is facing a new copyright lawsuit in the United States, this time over the music used to build its artificial intelligence.

According to Music Business Worldwide, the suit claims Nvidia trained AI models on songs from Jamendo, a music platform that is a subsidiary of Winamp, without getting permission to do so. GuruFocus reports that Jamendo is the company bringing the case against Nvidia, which trades publicly under the ticker NVDA.

The core of the dispute is consent. The sources indicate Jamendo alleges Nvidia used its catalog of music as training data — the raw material AI systems learn from — but did not have authorization to use that copyrighted material. The complaint is framed as a copyright matter, putting it in the same broad category as a wave of legal challenges aimed at how AI companies source the data behind their tools.

Beyond those points, the available source items do not provide further detail, such as the specific damages sought, the court involved, or Nvidia's response.

Why it matters: AI systems are only as good as the data they learn from, and a growing number of creators and rights holders argue that tech companies have been using their work without paying for it or asking — making cases like Jamendo's a test of whether that practice will hold up in court.
