Anthropic lyrics case goes to judge with no ruling yet
Judge Eumi K. Lee heard cross-motions on 499 songs for hours on October 21 and took the case under submission without saying which way she leans
Music publishers Concord, Universal Music Publishing Group, ABKCO and five others argued before US District Judge Eumi K. Lee in San Jose on Wednesday, October 21, 2026, that Anthropic's Claude competes with the songwriters it trained on, citing almost 120,000 prompts asking Claude to write "new" song lyrics. Anthropic's lawyer Sonal Mehta told the court users are the ones "pushing the button" when they ask for lyrics, and that Claude learns from "vast, vast amounts" of content rather than taking lyrics specifically.
Matthew Oppenheim, arguing for the publishers, said Claude reproduces their lyrics, sometimes verbatim, according to Courthouse News, and pointed to two kinds of output: mashups that mix real lyrics into Claude's answers, and "synthetic" songs written in an artist's style. Lee asked whether that argument would hand the publishers a monopoly over writing in an old song's style without a licence; Oppenheim did not back off.
No ruling, no deadline, no payout to chase this week — so the honest move is to watch, not panic. What's worth noting is what the publishers put on the table: almost 120,000 prompts asking Claude to write "new" lyrics, and an argument that mashups and style-alikes compete with the songwriters whose words trained the model. If you write lyrics or music-adjacent work, that's the argument to understand now, before any ruling forces you to react fast.
