Well, I thought it was bullshit. I don't deny that "the sounds have intellectual as well as emotional appeal," but that only applies to someone who can listen with the ear of a musician. So, for me, the whole thing was a self-serving exercise. Furthermore, he treats music as a thing in itself, but it isn't and it's at least as interesting to listen to music as an expression of a time and place. But is that something that musicians think of music? - that it's a thing in itself, without broader context?
