The complaint says songbooks and sheet music containing the lyrics of \"hundreds or more\" of their compositions were among the millions of pirated books Anthropic torrented from LibGen and PiLiMi, and that Claude can reproduce lyrics verbatim. It seeks up to $150,000 per work and an injunction.

Unusually, the complaint also names Amodei and\nMann as individual defendants, saying the torrenting would not have happened without their direction. It adds output claims\n(Claude reproducing lyrics) and DMCA claims about copyright-management information.\n\n## Why it matters\n\nThe authors' settlement released only claims of class members over listed books; rightsholders of other content in the same\ndownloads (music publishers here) are now suing separately, and Universal's Concord case from 2023 is still running. Naming the\nfounders personally raises the stakes before Anthropic's planned IPO.
