Sony and Warner Music sue Anthropic over alleged theft of tens of thousands of songs
Sony Music Publishing and Warner Chappell Music have filed a lawsuit against AI company Anthropic, its CEO Dario Amodei, and cofounder Benjamin Mann, alleging the company illegally downloaded, scraped, and torrented 'thousands upon thousands' of copyrighted songs to train its Claude AI models. The lawsuit, filed in federal court in Northern California, claims Anthropic obtained lyrics and sheet music from pirate sources like Library Genesis and scraped licensed lyric websites such as Musixmatch and LyricFind. The publishers seek statutory damages of up to $150,000 per willfully infringed song and $25,000 for each instance of removed copyright-management information, potentially reaching billions of dollars. Named songs include Marvin Gaye's 'Ain't No Mountain High Enough,' Mariah Carey's 'All I Want for Christmas Is You,' and the Beatles' 'I Am the Walrus.' Anthropic rejected the allegations, calling it recycled litigation, and pointed to a prior fair use ruling in Bartz v. Anthropic. This is the fifth music-copyright lawsuit against Anthropic, following a $1.5 billion settlement in September 2025 that the publishers deemed insufficient.

Sony Music and Warner Chappell sue Anthropic over AI training on copyrighted songs
Sony Music Publishing and Warner Chappell, divisions of Sony Group and Warner Music Group, have filed a lawsuit against AI company Anthropic, its CEO Dario Amodei, and co-founder Benjamin Mann in the U.S. District Court for the Northern District of California. The publishers allege Anthropic unlawfully copied tens of thousands of copyrighted songs to train its Claude AI models, using methods including BitTorrent downloads, pirate libraries, and scraping authorized lyric services. Songs cited include hits by Mariah Carey, Survivor, Leonard Cohen, Bon Jovi, and Taylor Swift. The publishers seek up to $150,000 per infringed composition and an injunction. Anthropic disputes the claims, arguing its use of copyrighted material for AI training constitutes fair use. A previous ruling in a related books case found that training on legally acquired books could be fair use, but creating a library from pirated books was not. The case could set a precedent on whether AI developers must license copyrighted material for commercial training, potentially creating a new revenue stream for music publishers or imposing significant costs on AI developers.
