To me it comes back to the fact that we're all wired differently when it comes to what music we like and how we want it presented. Some people have what I call "theory mind" and can consciously hear and appreciate all kinds of subtleties, harmonic and otherwise, that affect me only subliminally. I can see how for them anything other than a strict formal presentation of the music will be full of unwelcome distractions. They seem to be able to go straight from the cerebral to the emotional, not needing that visceral, almost physical, connection with the performance that I so enjoy.
The other thing to mention is that one of the great delights of blogging is the exchanges with other bloggers I follow, none of whom are music therapists. We have some mutual interests, but have different ways of talking about them, and that deepens and broadens my appreciation of various aspects of music making in ways I'd never expected.
