There are a finite number of musicians in the world. Most of them are working on music that either 1) appeals to them, specifically, or 2) appeals to enough of an audience that they can eek out a living. And chances are, if you're hearing it in public, you're getting #2.

I want music that appeals to me. My tastes are broad but not infinite, and I've already thoroughly plumbed the depths of my favorite genres - many of which are largely ignored by modern musicians (see #2 above). AI offers a way of getting new music for neglected or underdeveloped genres. Spanish language 80s new wave combined with reggae? Why not?

I listen to a lot of music across many disparate genres. I even play music (for fun). I have also enjoyed some AI generated music. It's not either/or, I can listen to both.
