Munich Court Rules Suno Infringes Music Copyrights, Sets European Precedent

Only the musical compositions were at issue in the case, not the lyrics, and the court found that the six tracks’ musical elements were memorized in Suno’s models, enabling outputs that could reproduce the originals.
The ruling covers both the training and output stages, rejecting the idea that ingesting material for training is protected activity and showing that memorization can lead to infringing outputs regardless of prompts.
The court applied US law to assess infringement and rejected Suno’s fair-use defense under that framework.
GEMA CEO Tobias Holzmüller described the decision as a 'verdict of global significance' and suggested it strengthens Europe’s stance on licensing AI training, potentially setting a continental precedent.
Tobias Holzmüller has stated that 'AI models based on the theft of intellectual property are not protected by law. AI providers must acquire licenses and may not use the works of our members free of charge.'
A Munich Regional Court has ruled that AI music startup Suno illegally used copyrighted songs to train its AI model and produced outputs that copied those songs, according to The Decoder and Crypto Briefing. The court ordered Suno to disclose revenues earned from the infringement and to pay damages, in what Germany's music rights group GEMA called a landmark ruling.
The case centered on six well-known compositions, including Alphaville's 'Forever Young,' Lou Bega's 'Mambo No. 5,' and Boney M.'s 'Rasputin' and 'Daddy Cool.' The Music reported that the court found Suno had memorized these works inside its model — meaning the AI could reproduce recognizable parts of each song when prompted.
Suno argued that its AI only learned general musical patterns from training data — not the songs themselves. The court rejected that defense outright. According to The Decoder, judges found that the six compositions were stored inside Suno's model weights. That means the AI could produce outputs that copied the originals, not just similar-sounding music.
The ruling covered both stages of AI development: training and output. The court held that feeding copyrighted songs into a model is not a protected activity. It also ruled that Suno — not its users — is responsible when the AI produces infringing content. Even simple or open-ended prompts did not break that legal link, Crypto Briefing reported.
In an unusual twist, the court applied US copyright law to evaluate Suno's fair use defense, since Suno is a US-based company. It still rejected the defense, according to The Decoder. Suno had claimed that training AI models on music is transformative — a key fair use argument — but the court disagreed.
Suno pushed back after the ruling. The company said the decision misreads both its technology and US law. Suno maintained that its goal is to help users create original music, not copy existing works. The company indicated it may appeal, The Music reported.
GEMA, Germany's largest performing rights group, brought the case on behalf of its members. CEO Tobias Holzmüller said the outcome sends a clear message: 'AI models based on the theft of intellectual property are not protected by law. AI providers must acquire licenses and may not use the works of our members free of charge.' He called it a 'verdict of global significance,' according to The Music.
The ruling may limit how AI companies use the European Union's text-and-data-mining exemption, which some firms had cited to justify training on copyrighted material. Crypto Briefing noted the decision could set a continental precedent — pushing AI music companies to negotiate licenses before training on catalogued music.
As part of the ruling, Suno must hand over financial records tied to the infringing activity. Boca Raton Tribune reported that the court found Suno had no right to process GEMA-represented songs without a license. The exact damages figure will be set in a separate proceeding.
The case is part of a wider clash between AI firms and the music industry. Similar fights have targeted OpenAI and other AI developers. The Munich ruling adds legal weight to the argument that AI companies cannot train on protected music for free — and that doing so carries real financial consequences.
