Cool track. I quite like the bass sound, and the beat. I'm not a big fan of repetitive vocal samples -- I know some people go for it, but to me it's a little too much repetition. If it were me I'd probably cut out every other sample, so it's alternating with the beat.. That way there'd be little breaks where it's just music. That would provide a little more call/response sorta action.

 One other thing you might consider *if* you want more clarity in the sample, is to duck the delay -- sidechain it to the clean signal.

Good stuff, nice work. :-)
