On top of that, music was not a commodity back then. Live performances literally made a living for many of them as these performances were the only source of music. (And a church needs this music for every mass, for instance.)
Now music is abundant, recordings are cheap / free, and the best performance is easily available in a recorded form. Live performances are still a thing and still feed many of the music creators. Royalties, too. But you better be a superstar for that to bring enough. (Liszt and Mozart were superstars, in a sense.)
Wait until a Dall-E equivalent for music emerges though.
A DJ will arrive with a unique set, likely with every track custom-made for a given gig.
Selling any records at all will become very-very hard, except for rare hits with outstanding human vocal performance. In music clips, music will be relegated to the position of a movie soundtrack, if not lower.
Obviously for anything sort of focus-y, house music downtempo etc. If we're not already there, we'll probably be there soon, though I am curious if a careful listener will eventually notice the uncanny valley problem there. But pop music I'd say has two problems. 1. There's a je ne sais quoi quality that's hard to replicate, and two I imagine the corpus is just not that big. I mean sure, there's a decently large corpus of pop music, but good pop music? how many hip hop billboard charts have there been a thousand, maybe a few thousand. How do you combine Beyonce, Janet Jackson, Mariah Carey and Whitney Houston into a banger that doesn't sound too much like Beyonce', Janet Jackson, Mariah Carey and Whitney Houston without the titular character marketing said music.
One of the new genres that really impresses me, is 3D art. The art form is getting quite mature, and often requires as much work as any Dutch Master oil painting.
One of my favorite 3D renderings, is Worth Enough, by radoxist[0]. Nowadays, I'm sure that there are works that beat it, but it was quite amazing, when he posted it.

Ppl also dont see art where it is in its pure form -Engineering.
