Not a valid comparison, I feel. I may be hindsight, but rap and electronic music came from vibrant underground scenes and to many critics and music fans of the time was seen as at least interesting and at best ground breaking.

AI music on the other hand comes not from the underground, but from corporations. You'll be hard pushed to find any critics or music connoisseurs singing its praises.

It's hindsight. At the time it was a pretty mainstream opinion that it wasn't music at all, just talking over fake drums and stolen copies of other people's songs.

The culture changes.
