wow, how good is that aleem! one of the reasons this music sounds so good to me and resonates so strongly is that i first came across a lot of this stuff as samples in hardcore, jungle, 2-step, hiphop etc.... like the first one i posted, body fusion, i'm sure those strings were on some jungle record or other....
it also means the boundaries do blur for me, r&b, house, freestyle, electro (at least with vocals) its all r&b plus new technology.... it all sounds so good.
(can't do jazz funk though, doesn't work for me, unless the miles davis stuff counts)
