Look at Max Martin - his songs are massive hits because they are highly engineered and use a proved Swedish recipe / formula / composition techniques (ex: balanced lines) that on paper are actually quite simple. On paper.

If it were as simple as it looks, everybody would be a Max Martin or somebody would train an AI on his canon and maybe actually have something decent. Music is based in emotion, and the bits and bytes aren’t close to simulating anything close other than probably raw schizophrenia.

The current state of AI music? There’s no amount of money you could pay me to listen to it for an hour a day for a week. No way. It’s that bad.

Counterpoint: a moderately musically inclined person with Propellerhead’s Figure can come up with more pleasing and coherent music on their third or fourth try that would put any of these to shame. It’s just reality at present.
