I'm disappointed ___ isn't on the lineup

Also, the gaslight anthem. I was surprised they weren't on the lineup

Chic Motorhead and Flume

Beck and Outkast are the obvious answers.

Beck is playing other festivals, not sure if Bonnaroo simply passed on him or if the schedule simply didn't pan out.

On the other hand, it seems like AC/Superfly simply dropped the ball on Outkast. Outkast is booked at every festival in the world, and I know others have speculated it might have been a matter of a radius clause with another festival. However, Bonnaroo should have been waiting at the front of that line. Outkast has been one of the most common headliner requests for years on this board. Inforoosters were clamoring for Outkast when it was irrational to clamor for Outkast. Now they're finally back and we miss out.

I can understand a desire to differentiate from other festivals and strive for a unique lineup, but Outkast just seemed like such an obvious (and apparently relatively inexpensive) get. I'd be really interested to know what went into that decision.

I promise I won't turn every post into Kanye, but did they not see the results of the Kanye vs. Outkast poll? Outkast won by multiple landslides.

Band of Skulls
Beck
Fidlar
Deer Tick
Moon Taxi
St. Vincent

Fuck I just realized there's no tyler, the Creator or Earl sweatshirt

MMJ, I was really hoping for them, maybe next year.

Beck
Outkast
My Morning Jacket
Between the Buried and Me
St. Vincent
Sun Kil Moon
Run The Jewels
Mogwai
Queens of the Stone Age
Fatboy Slim
Motorhead
The Black Angels

Figured they'd go all out with Eric Prydz or Armin Van Buuren as the main EDM guy, unrealistic though.

+1

Also surprised Outkast isn't in the line up, but I am sure I will see them somewhere. 

Also wish Sleater-Kinney would reunite on the Farm. 
Always disapointed that Bowie isn't in the line up. 

Sun kil Moon

There are others I am disapointed about, but knew they wouldn't because they are playing elsewhere that weekend such as:
St. Vincent
Arcade Fire

Foo Fighters
Beck
Prince
Band of skulls

The line up is good. Lots of folks I'd like to see. I feel like they were swinging for a big third headliner and missed.

Motorhead.... mostly because my boyfriend was super excited at the opportunity to see them. He gave me SHIT for that hole in the lineup.

London Grammar?

honestly though, I gave the lineup a quick listen and between the straight forward rock of Arctic Monkeys and the fucking crazy Bouncing Souls, I'll be okay without my Foo

Childish Gambino, Beck and Jagwar Ma. Hard to complain about this lineup though.

Avey Tare or Panda Bear. I need something Animal Collective related.
