I have never heard of Dubstep. According to wikipedia -
Dubstep is a genre of electronic dance music that originated in South East London. Its overall sound has been described as "tightly coiled productions with overwhelming bass lines and reverberant drum patterns, clipped samples, and occasional vocals".
Wouldn't that mean it's similar to techno? Only asking 'cause I don't know.
I don't really care for genres if the song gets my heart pumping and my penis erect then it's some good music. It only depends on what for example, if i am doing work i love to listen to some smooth classical music. (Don't judge me) whereas if i am playing my PS3 i listen to mental/rock gets me in that zone if you know what i am saying. =D
