Really don't think this is a 3rd drop like people are saying. The whole thing would be muted in the exit festival live set if it was. This is the only part you can hear on the yt upload. Also not the same as the Xena 140 drop either
If this is actually a third drop for Push like people theorise and not either just another tune with the Push sample on or a separate live VIP then I swear this might be my favourite Skrillex tune
