Winamp Group<\/strong>\u2018s music licensing subsidiary Jamendo<\/strong> has filed a copyright lawsuit against generative AI music company Suno<\/strong>.<\/p>\n The complaint, which you can read in full here,<\/a>\u00a0was filed in a US federal court in Massachusetts<\/strong> on Monday (June 29<\/strong>) against Suno, Inc.<\/strong><\/p>\n The lawsuit comes days after Jamendo<\/strong> sued chipmaker Nvidia<\/a> in the United States, and is the second copyright complaint the Winamp<\/strong> subsidiary has brought against an AI developer in under two weeks.<\/p>\n The complaint relates to the alleged unauthorized use of musical content and associated data operated by Jamendo<\/strong> in the development and operation of AI technologies, Winamp Group<\/strong> said.<\/p>\n It includes claims for copyright infringement, breach of contract and unjust enrichment, as well as unfair and deceptive business practices under Massachusetts<\/strong> law.<\/p>\n The copyright claims are brought under the US Copyright Act<\/strong> and seek monetary damages and injunctive relief, according to the company.<\/p>\n In the complaint, Jamendo<\/strong> says Suno<\/strong> \u201cblatantly disregarded\u201d its intellectual property rights by using its catalog and data to develop its AI platform \u201cwithout any authorization.\u201d<\/p>\n The case centers on the MTG-Jamendo Dataset<\/strong>, a research collection of more than 55,000<\/strong> tracks that Jamendo<\/strong> built from its catalog around 2019<\/strong>.<\/p>\n The US Copyright Office<\/strong> issued a registration for the dataset on June 17<\/strong>, according to the complaint.<\/p>\n The complaint alleges that Suno<\/strong> used the dataset to train its AI, including an early open-source model called Bark<\/strong> that it says was built in part on roughly 919<\/strong> hours of Jamendo<\/strong> audio.<\/p>\n Jamendo<\/strong> made the dataset available for non-commercial research only, and says any commercial use requires a paid license from the company.<\/p>\n Suno<\/strong>\u2018s use of the data to train a commercial AI system fell outside that grant and amounts to \u201cwillful\u201d copyright infringement, the complaint says.<\/p>\n Citing Suno<\/strong>\u2018s own public statements, the complaint says the company \u201cembraces the view that \u2018impatience is a virtue’\u201d and emphasizes \u201cextreme speed\u201d in building its service.<\/p>\n Jamendo<\/strong> says it invoiced Suno<\/strong> for the unauthorized use on September 29<\/strong> last year, and that Suno<\/strong> confirmed receipt by October 3<\/strong> but did not pay.<\/p>\n Jamendo<\/strong>\u2018s Belgian counsel sent a formal notice of default on October 14<\/strong>, the complaint says. Jamendo<\/strong> is seeking an injunction, plus actual damages and Suno<\/strong>\u2018s profits of \u201cno less than\u201d \u20ac17.8 million<\/strong>, according to the complaint.<\/p>\n In the alternative, it is seeking statutory damages of up to $30,000<\/strong> per infringed work, rising to $150,000<\/strong> per work where infringement is found to be willful.<\/p>\n That Nvidia<\/strong> complaint was filed on June 22<\/strong> in the US District Court for the Northern District of California<\/strong>.<\/p>\n It accuses the chipmaker of training two of its AI audio models, Fugatto<\/strong> and Audio Flamingo<\/strong>, on the same MTG-Jamendo Dataset<\/strong>.<\/p>\n Jamendo<\/strong> says the proceeding against Suno<\/strong> is separate from the Nvidia<\/strong> case, but that both raise similar issues over the alleged unauthorized use of its content to develop AI.<\/p>\n The dispute with Nvidia<\/strong> has also reached a court in Belgium<\/strong>, where the Ghent Enterprise Court<\/strong> confirmed its jurisdiction in June over a related commercial claim of about \u20ac16 million<\/strong>.<\/p>\n Jamendo<\/strong> had publicly threatened legal action<\/a> against both Nvidia<\/strong> and Suno<\/strong> in 2025<\/strong>.<\/p>\n Jamendo<\/strong>\u2018s suit adds to the copyright litigation Suno<\/strong> already faces in the US and Europe.<\/p>\n Suno<\/strong> remains in litigation with Universal Music Group<\/a><\/strong> and Sony Music Entertainment<\/a><\/strong>, which are seeking to add more than 61,000 recordings<\/a> to their case.<\/p>\n That major-label case is being heard in the District of Massachusetts<\/strong>, the same federal district where Jamendo<\/strong> has now filed.<\/p>\n Suno<\/strong> also faces separate copyright suits from Denmark\u2019s Koda<\/a> and Germany\u2019s GEMA<\/a><\/strong>.<\/p>\n
