Agreed.

Another side of it is that it will enable the creation of more music around more topics than before, by non-musicians. The accessibility bar is lower.

For a lot of people, music is a way to express their emotions, and not just by creating/playing it, but by listening to it. Now, you'll be make your own hyper-specific music with lyrics around topics specific to you, without learning any of the underlying skills yourself.

I've certainly wanted some kinds of music/representation in music of some of my experiences to exist, but not enough to go out and learn to make it myself. Now/soon I should be able to do that with AI tools, and I think that's actually neat!
