i've heard Techno DJ's play the theme song from Star Wars, does that make the theme from Star Wars a techno song?

i've heard dubstep dj's play Basic Channel (see the above mix), does that make Basic Channel Dubstep?

and no, i don't consider Horsepower to be dubstep. an influence on dubstep, and perhaps proto-dubstep, but not dubstep.
