The human performance at the bottom of the page was nice. But you can also give a great musician a zipper and paper bag and they can make it sound nice.
It’s just like LLM generated prose to me. The orchestration and motif development is musical sounding, but there’s these artifacts that are like the “It’s important to consider” or “Would you like further suggestions” of the aural world.
I think it would be fun to write up a detailed analysis of a full piece.
