Anthropic’s Lyrics Fight Turns on Whether Claude Competes With the Music It Learned From
The fight began in 2023, when publishers led by Concord Music Group sued Anthropic, alleging that Claude was trained on copyrighted lyrics and could return protected material without paying the rights holders. The publishers say that matters not merely as a technical copyright question, but as a threat to the licensing business: lyric websites pay to reproduce songs, while an AI answer can bypass that market.
They have pointed to outputs they say cross the line from inspiration into copying. In one example cited in court papers, an investigator asked for “a song about the death of Buddy Holly,” and Claude allegedly produced the lyrics to Don McLean’s “American Pie” verbatim. Concord is seeking up to $150,000 for each of 499 songs it says were infringed, plus potential damages tied to allegedly removed copyright notices.
Anthropic’s answer is that training on lyrics is protected fair use: the works were part of a far larger training corpus, not material Claude was built to reproduce. Its lawyers also say the company added copyright-protective guardrails and that a user who defeats them bears responsibility. “When a system ‘creates the copy only in response to the user’s command,’ its operator does not engage in volitional conduct,” Anthropic argued. “The user does.”
At an Oct. 21 hearing in San Jose, U.S. District Judge Eumi Lee heard extensive arguments but did not finish the parties’ motions, asking them to consider additional hearing dates. The case sits alongside a separate publisher suit accusing Anthropic of using more than 20,000 works obtained through torrent sites—and follows a $1.5 billion book-publishing settlement in which a judge found AI training fair use but faulted the acquisition of pirated copies.
The central split is stark: publishers say Claude erodes the value of human-created music; Anthropic says a costly AI model is hardly “the world’s most expensive lyric-generating machine” when the same text is readily available through search.
