"Creating a permanent, general-purpose library was not itself a fair use excusing Anthropic's piracy."

> buying, physically cutting up, physically digitizing books, and using them for training is fair use So Suno would only really need to buy the physical albums and rip them to be able to generate music at an industrial scale?
Anthropic doesn't take books and use them to train a model that is intended to generate new books. (Perhaps it could do that, to some extent, but that's no its [sole] purpose.)
But Suno would be taking music to train a model in order to generate new music. Is that transformative enough? We don't know what a judge thinks, at least not yet.
