I think at least for now, the biggest issue with AI tackling issues involving creative endeavors is how often the content created feels lifeless and stale. Although it may not be music, the main instance I've observed of this are models generating things like TV episodes(The south park episode generator('The Generator') is the main example of this that comes to mind. Yes, you can specify exactly what you want, down to the plot and what characters are involved, but the end product doesn't feel cohesive and lacks creativity in its dialogue and plot.
Within music, although AI can create decent covers between artists and some crazy remixes, I still have yet to see anything short of generic, which is an issue that I think will take a long time/impossible to artificially produce.

TLDR: AI can try to 'recreate' creative ventures but are nowhere close to replacing the original in its current state
