The interesting thing about music is that tastes changes over time, and it is rather fun to find a song you hated when released, which you now love, sometimes partily due to the fact that you hated it in the first place.
Another issue with AI music is that it can't really surprise you, if everything is generated for you, the created music will just become more and more narrow in scope as you keep listening to the same slop causing the models to keep regurgitating the same shit, but more "refined".
There are plenty of times when I have heard a completely new song from a genre I haven't really liked before, only now, i love it.
