The publishers allege the AI company misused hundreds of copyrighted song compositions to train its **Claude** models.\n\nThe complaint names songs by **The Beatles**, **Taylor Swift**, and **Michael Jackson**, among others. Sony and Warner claim Anthropic obtained lyrics and sheet music through torrent downloads without permission.\n\nThe lawsuit seeks up to **$150,000** per infringed work. It also asks for a court order blocking Anthropic from using the publishers' catalog. This case adds to a growing wave of copyright litigation against AI developers.\n\n## Anthropic's Legal Battles Escalate\n\n**Universal Music Group** filed a similar suit against Anthropic in **2023**. That case remains unresolved. Anthropic settled a separate class action with authors last year for **$1.5 billion**.\n\nSony and Warner argue that settlement was insufficient. They state that Anthropic treats infringement as a business expense. The complaint highlights Claude's ability to reproduce lyrics verbatim when prompted.\n\n\"Anthropic clearly considers that to be just the cost of doing business given that its entire business model continues to be built on copyright theft,\" Sony and Warner said in their complaint. \"And $1.5 billion is obviously not a large enough settlement to deter infringing conduct by a company that has parlayed such mass infringement into a staggering $2-trillion-dollar valuation.\"\n\nThe publishers also claim Claude generates new lyrics that compete with original works. They call these outputs harmful market substitutes. This argument could shape how courts view AI-generated content.\n\n## Copyright Law Meets AI Training\n\nTech companies face mounting legal pressure over training data. Authors, news outlets, and music labels have filed multiple suits. The core question is whether using copyrighted material for AI training constitutes fair use.\n\nAnthropic's alleged use of torrent downloads may weaken its defense. Courts have been less sympathetic to defendants who obtain data through unauthorized channels. The complaint suggests Anthropic knowingly accessed pirated files.\n\nSpokespeople for Anthropic, Sony Music, and Warner Music did not immediately respond to requests for comment on Monday. The outcome could influence licensing practices across the industry.\n\nSeveral AI companies have begun negotiating content deals with publishers. Others face injunctions that could force them to retrain models. The music industry's aggressive stance signals broader resistance to unlicensed training.", "url": "https://wpnews.pro/news/sony-warner-music-sue-anthropic-over-songs-used-in-ai-training", "canonical_source": "https://insideai.news/news/ai-policy-and-regulation/sony-warner-music-sue-anthropic-ai-training/9449/", "published_at": "2026-08-31 15:06:21+00:00", "updated_at": "2026-08-31 15:23:15.515571+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-policy", "ai-ethics"], "entities": ["Sony Music", "Warner Music", "Anthropic", "Claude", "The Beatles", "Taylor Swift", "Michael Jackson", "Universal Music Group"], "alternates": {"html": "https://wpnews.pro/news/sony-warner-music-sue-anthropic-over-songs-used-in-ai-training", "markdown": "https://wpnews.pro/news/sony-warner-music-sue-anthropic-over-songs-used-in-ai-training.md", "text": "https://wpnews.pro/news/sony-warner-music-sue-anthropic-over-songs-used-in-ai-training.txt", "jsonld": "https://wpnews.pro/news/sony-warner-music-sue-anthropic-over-songs-used-in-ai-training.jsonld"}}
