I was thinking about this - what if someone trained a stable diffusion type model on all of the worlds commercial music? This model would probably produce quite amazing music given enough prompting and I'm wondering if the music industry would be allowed to claim copyright on works created with such a model. Would it be illegal or is this just like a musician picking up ideas from hearing the world of music? Is it really right to make learning a crime, even if machines are doing it? I'm conflicted after finding out that for sync licensing the music industry want a percentage of revenue based on your subscription fees, sometimes as high as 15%-20%! I'm surprised such a huge fee isn't considered some kind of protection racket.
