Music publishers and Anthropic argued cross-motions for summary judgment over Claude and song lyrics on 21 Oct 2026, with no ruling yet.

Two US judges ruled in June 2025 that training language models on books was fair use, but only on the records in front of them, and one said plainly that most such copying will likely be illegal.

A federal judge in Manhattan has let two voice actors pursue New York publicity, consumer-protection and contract claims against Lovo, the AI voice company they say cloned them, while dismissing most of their trademark and copyright claims. This was a ruling on a motion to dismiss, not a win at trial. Its reasoning still matters to singers: in this court's view, copyright in a recording doesn't protect the voice on it, but New York's civil rights law does.
