How is dubstep different from dub or psydub? Dubstep is supposed to be a fusion of dub and UK garage (or "2Step") - that is, dub with RnB and ragga vocals, different kinds of drum effects like reversed drums and shuffling drum loops, and much overuse of that turntable "spinback" effect. Dubstep is mostly instrumental, though - at least, what I've heard has been. Oman's track was very nice and all, but I didn't really hear much dub reggae or garage. To me, it had more of a kind of ambient vibe. I've never heard of psydub, so can't help you there. Honestly, all these minute deviations of genres that get their own name is starting to confuse me.
