I support sillyrob.
Dubstep is taking 10% of the orginal song, spreading it out, and adding a bunch of
WUBWUBWOBWOBWUBWUBVROOOOOOMZZZZZWAHHHHHHH inbetween.
For example, when the "Friday" craze was all up and about, I remember watching this. The first 30 seconds sound fine, even good. But it is all decieving. Immediately after the song is non-stop VROOOOM VROOOM WOB WOB WOB WOB WOB VROOOM VROMMM WAHHHHH with little sound bits thrown in.
