We recently looked at collaborations that we feel didn't need to happen. While many of you agree, there was some discussion about A$AP Rocky and Skrillex's "Wild 4 the Night," both internally and out there in the public. There's just something about hip-hop and dubstep acts coming together that we feel needs to be done right (meaning an actual collaboration) or not done at all. That got us thinking: which rappers do we really want to see working with dubstep artists? Which MCs could give a proper performance over that style of beat, and still keep their core fans interested? Here's our list of rappers that we actually want to hear on some dubstep.
