Suno Loses Copyright Case in Germany, Must License Music for AI Training

A Munich court ruled that AI music platform Suno infringed copyright by training its models on music represented by GEMA without a license, rejecting Suno's jurisdictional, fair-use and transformative-use defenses. Suno must now disclose revenues tied to the infringement so damages can be calculated, in one of the first major European rulings on AI training data.

On July 31, the Munich Regional Court ruled that Suno, the US-based AI music platform, violated copyright law by using music represented by GEMA, Germany's largest performing rights organization, to train its generative models without proper licenses. It is one of the music industry's most consequential legal wins against AI to date.

The ruling requires Suno to disclose revenues linked to the infringement so that damages can be calculated — meaning the final penalty will scale with how much money the company made from the unlicensed training data.

GEMA filed the lawsuit in January 2025, targeting Suno's use of specific copyrighted tracks during training, including Alphaville's “Forever Young” and Lou Bega's “Mambo No. 5” — not obscure deep cuts, but widely known songs.

The court found that Suno copied and internalized copyrighted music during model training: the AI ingested actual copyrighted recordings to learn how to generate new music, which the court decided crosses a legal line.

Suno challenged the court's jurisdiction, argued fair-use principles, and claimed its output was transformative enough to sidestep copyright restrictions. The Munich court rejected all of those defenses.

GEMA represents roughly 95,000 German songwriters and more than 2 million rights holders globally, and presented evidence that tens of thousands of protected works were used in Suno's training pipeline.

Germany is not Suno's first courtroom: the company has faced class-action lawsuits in the US over similar allegations and previously reached a settlement with Warner Music Group.

This is one of the first major European court rulings on whether AI companies need licenses to train on copyrighted creative works, setting a precedent that could reshape how AI companies handle creative content. The open-books order means damages will scale with Suno's revenue from the infringing activity — and the decision is likely to encourage other European rightsholders and accelerate pending US litigation, pushing AI music firms toward licensed training.

Why it matters

The ruling sets a key European precedent on AI training data, and a damages model tied to revenue could push AI companies toward proactive licensing deals while shaping copyright litigation against generative AI worldwide.

Bedrock Data launches Agent DLP to police data flowing through AI agents

Bedrock Data has launched Agent DLP, a data loss prevention product for AI agents that inspects every request and response an agent exchanges with software tools and applies access and regulatory policies in real time. The launch is backed by research showing machine identities used by agents typically hold far broader access to company data than human employees.
