The entire point of piracy and related copyright infringement is to build a path to appreciation of an artist's works without necessarily agreeing to their pricing and terms (whether imposed by the artist themselves or by publishers). What you are suggesting is the complete opposite: leveraging established or even defunct artists as mere brands to slap on generic machine-generated content that does a great job imitating said artists' style, but bears no resemblance whatsoever to the actual creative process that led to that specific style in the first place.

Record labels would actually love this model: they'd be able to put their extensive back catalogs to use by giving everyone their very own hyper-personalized, maximally-stimulating Beatles, Queen, Linkin Park and more, all without paying a single cent to the humans who actually built those acts. What breaks this utopia, and what you seem to be missing here, is that by far and large people want to listen to the real deal and not to a deepfake Chester Bennington's song on the Israel-Palestine conflict in an unprecedented act of VC-funded digital necromancy.
