As an avid dubstep listener, it never gets old to me, as there are so many different styles of dubstep and then other genres that sound similar to dubstep but have a few fundamental changes. In terms of artists, I'm pretty mainstream about it.
Some Favorites: Skrillex, Skism, Eptic,Dirtyphonics, Habstrakt, Kill the Noise, KOAN Sound(They make glitch hop too

), and Pegboard Nerds.
