My advice would be don't go for the obvious everytime when sampling. If you hear something you like that you want to sample, give it a chance and see where it leads. Sometimes i'll force myself to sample off of one record and just make something off of it. People get caught up in the "Oh it's gotta be funk, r&B, soul, etc." Nah man, that stuff is good too but it's played out if you aint really digging for the real stuff. Every man under the sun is sampling that same stuff unfortunately. Or maybe fortunately? because its slowly helping people progress to different sounds.
