you don't find the way a given piece of music sounds changes according to what has happened since you first heard it? It just gets sealed in time and can be repeated again and again without deteriorating or warping in any way?
i think it's that what attracted to me to a particular piece of music was how much "mana" it contained.
so although, yes, some pieces of music have a bit of a zeit fingerprint for me - the things i really value tend to be perennial favourites. with them it's a bit like holding a jewel in the palm of one's hand and every now and then turning it to look at a different facet. i'll often find different things i can appreciate in the more luminous music - things i hadn't heard or appreciated before - they're that rich.
with regards to the miles davis - there is a bit of that "flavour" that pungent cheesiness of those generic jazz markers (not SO much) but that's what i always liked about ardkore - its flavours. there's that tendency always with the "hip" avant-garde to strip everything out and you're left at the end with music for accountants. you get to see the audience for that scene and they're a most unsexy bunch with no style.
