I just read the entire post, so what the heck...

Here are my favourites:
melodic electronics: orbital/bt/underworld,....
jazz: atmospheric jazz, I very much like Jan Garbarek
I like ambient with variation or  deep atmosphere - (check \"liquid morphine\")
modern folk
and modern classics - not to much dissonance please -
furthermore I like funk with an attitude - \"this funk is of the hook\"
and about all alternative classics
and anything with a challenging groove
