But AI does seem to make it easier.
Also not that it takes skill to come up with a remix/cover/homage of a song that is close enough to the original that people can enjoy it like the original, but not so close that you are just plagiarizing it. So this problem before AI is limited to talented musicians who for some reason would rather copy somebody else then to make their own music.
IMO they need to focus on the scam side more than the AI side.
