At the radio station where I work we get sent dubstep all the time. We tend to be really slack at getting around to filing it because we know nobody, not even the dance DJs, are ever going to play any of it. Anytime anything comes in that nobody is really interested in it gets to sit in the "dubstep ghetto" along with all the dubstep CDs. Once in a while the rubbish man comes and takes all the unwanted CDs away. I could try and find out where they go if you like, but the problem is that nobody keeps track, because nobody cares. Dubstep - not big around these parts.
