I'm honestly surprised at the dislike for Skrillex at the top. Way worse EDM option. Acts just near the top of the bill or topping rhetoric respective genre for me. 21p Imagine Dragons Chainsmokers Calvin Harris Drake Wiz Khalifa G-Eazy
was an abomination when it was announced, and it's aged even worse.
Although.. Kendrick and Florence were 4 and 5, and they're bona fide headliners now, so I don't know. I'd kill for a lineup like 2015 at this point.
I also can respect Joel, and I'm a Deadmau5 fan. They wouldn't be on my short list, but I'd have them over Calvin, Drake, Mumford, RHCP, Kings of Leon, Imagine Dragons, Pearl Jam, and maybe some others who've been headlining festivals lately.
