As we move to a world where art is totally devalued, the early returns are not promising at all imo for AI generated music. It doesn't seem to make great art, but to allow talentless people simulate great art for cheap. It doesn't seem to inspire humans at all, it just makes them annoyed and angry.
Its primary use case to me seems to be "create royalty-free music for my amateur tiktok/youtube video that sounds how I want it to sound." That's valuable as long as the royalty-free thing exists, but no one is sitting around excited about the idea of prompting AI-Tupac rap to about them or their personal interests.
