Skrillex has releases a lot of good songs in his recent album and EPs, but did you guys know he actually has a LOT of other songs that he's never released? This may be because he thinks they're not good enough, is too busy, were on his laptop when it was stolen, and other various reasons. But the truth is a lot of these songs are actually really good. Check out this page http://skrillex.wikia.com/wiki/Unreleased_Songs to see all of them, and feel free to post which unreleased songs of his are your favorites. My personal favorites are his remixes of In For the Kill by Le Roux and Alejandro by Lady Gaga.
