Duuuuuuuude. Art is whatever you waaaaant it to beee.. Poetry is like, eeeeverywhereee. Duuubsteeep is self expression if the form of wuuuubwuuuuubwuuuuubwuuuuuubwuuub because it eexpreeeesess like soooo muuuuch emoooootion and shit.
/Fuck you whoever says dubstep is music/a form of expression. Dubstep is industrial music. It is made for clubs and shows. It does not tell a story, provide any insight into social or personal issues, and does not evoke any strong emotion. It also takes no talent to produce, and requires no knowledge of music.
Saying dubstep is music is on par with saying Yoko Ono was a genius.
