I think its a pretty good lineup. Personally I could care less about the headliners most years. I would go for the indie bands like Flaming Lips, Deadweather Phoenix. LCD Soundsystem, Avett Brothers, The National, The Black Keys, She & Him, The xx, Dan Deacon, Dr Dog, Punch Brothers, Blitzen Trapper, Japandroids, Edward Sharp, Ingrid Michaelson, The Dodos, Carolina Chocolate Drops, Tokyo Police Club and Neon Indian.
To my tastes, that is the best lineup they have had so far. I've never been just because I don't really like being in the middle of 80,000 people in the Tennessee summer heat.
