That's not how it works, as far as the spelling goes. Sorry. And if you don't "know" Skrillex you have no business commenting on dubstep's popularity, let alone in the mainstream.
If I don't know these Sky Relic people than they must not be popular.
Britney already did that with HIAM and several critics stated the same. But I am looking forward to his new music none the less, but he def. isn't bringing a dubstep influenced sound to mainstream. That's not subjective.
