First, I should verify the release of the EP. Skrillex's "Leaving" EP was released in 2014. I need to confirm the track listing. The EP includes "i---," "Scion," "Skrillex," and maybe other remixes or collaborations. Wait, actually, checking sources, the EP "Leaving" is part of his "Bangarang" album era. Let me double-check the exact tracks to ensure accuracy.
