That’s kind of how the music industry produces music these days. There are a few song writers that write for most artists, music producers who sample other music to string together songs for most artists etc. That’s why most music sounds the same and why AI generated music can be indistinguishable from mainstream music.

I mean, it was how Beethoven did it with dice, too. This is just much quicker and more comprehensive.
