Well this pairing sure works well. Wale joining forces with Skrillex to produce one hell of a track, "Trung." Clearly, hip-hop and dubstep can go together quite well.
On a tangent, apparently dubstep and Disney also go together well. This last weekend, it was announced at Comic-Con that Skrillex would be providing the soundtrack for Disney's latest film, Wreck-It Ralph. I've seen the preview and it looks like it's actually going to be quite a dope movie.
