I think you provide a great answer to your own question! Despite the fact that Bateman seems to develop his interests in music more by devoting whole chapters to it, this still ties into Bateman's shallowness as a person as well as his larger obsession with capitalist consumer culture. He is a character that lacks emotional depth and Ellis wants us to be aware how little he feels as a person. Even his musical interests, which are all notably the top-10 artists of the 80s, are meant to highlight not only Bateman's sheer apathy but also his investment in consumerism. Why? Notice how didactic his descriptions of the music sound. He almost sounds a bit like a recited text book or a pedantic critic, not someone who is entirely invested in it simply because he enjoys the music. I think you're right to notice that Bateman in American Psycho appears to value music above all else, but notice the things Bateman focuses on (e.g., offensive clothing, the club, and even the laughable scene with the business cards!). It all ties into who he is as a character for sure and your observation is spot-on!
