I put together this mashup when I realized there were no goofy dubstep remixes of this classic Dance Dance Revolution track. It turned out more awesome than I expected! The source song is “Butterfly” by Smile.DK, and the backing track is Skrillex The Sadness Will Never End [Bring Me The Horizon]. I even made that cute pic of Skrilly and Deadmau5 playing DDR with art I found on google image search. Cute-tastic and dub-alicious.
