I don't know about the quality part of musical reproduction, but it is interesting to me that the blues, or jazz, use the "blue note", which to me is usually a note that you don't expect to hear, but when you do, although it comes out of left field, it sounds right! So, it may be, that music becomes more musical when there is that degree of expectation and when a musical note or passage thwarts that expectation (in a pleasant way), voila, that was cool!
Avant-Garde jazz can be babbling (stream of notes, pardon the pun) and sometimes it (musical expression) feels more real when there is less of a connection to expectation, just depends on the music and the listener! Interesting article!
