Nvidia just picked up its eighth copyright lawsuit related to AI training data. This time, Luxembourg-based music platform Jamendo is the one swinging, alleging that Nvidia hoovered up hundreds of thousands of audio files and metadata to train its generative AI models without proper authorization.
The federal copyright suit was filed on June 22, 2026, in the US District Court for the Northern District of California. Jamendo is seeking a minimum of 17.8 million euros, roughly $20.3 million, in damages. But the real number could climb much higher: statutory damages could reach up to $150,000 per infringed work.
What Nvidia allegedly did
At the center of the dispute is something called the MTG-Jamendo dataset. It consists of approximately 55,000 full audio tracks, developed through a collaboration between Jamendo and the Music Technology Group at Universitat Pompeu Fabra in Spain.
That dataset was released under a Creative Commons license, but specifically for non-commercial research use. Jamendo alleges Nvidia took those tracks and fed them into two commercial AI products: Fugatto, a generative audio model, and Audio Flamingo, an audio-language model.
