possibility the popularity of mainstream rap songs being mixed with DJs, notably David Guetta on a lot of big artists songs adding the electro and trance feel to mainstream rap.
may have highlighted DJs more > electro music > DnB > Dubstep > glitch > etc. ?
just an idea
Datsik, Liquid Stranger, Nero, Bassnectar, Excision, Prettylights, Doctor P, Trolley Snatcha, Caspa, Rusko, Bare, Apajai... That's a base of artists, PM me for some more

They combine alot of awesome electro songs into one mix and it's all free. If u want good dubstep check out their mix called "Peace, Love, and Dub"
this man is correct, good dubstep is out there
