djcorea, I think you've captured the main flavours of d+b there, apart from more mellow Bukem-type stuff.
To be honest I think it's a bit pedantic to split it up any more than this. Otherwise you might as well label every track with a different style. Besides, an interesting DJ will cross several borders - e.g. when I saw EZ Rollerz, his stuff ranged from quite jazzy stuff (which I'm not as keen on) to some very nice dark hardsteppy stuff.
Agreed, "intelligent" is an utterly pretentious label.
