5) Rage Against The Machine
4) Fall Out Boy
3) Muse. Simply legendary.
2) Biffy Clyro. Most underrated band in existence.
1) Enter Shikari. While I listen to other bands music much more regularly, nothing beats a Shikari gig live, or the feeling of solidarity among fans.
Honourable mentions: Linkin Park, Pendulum, The Devil Wears Prada, You Me At Six, Deadmau5, Chase & Status, Skrillex, Foo Fighters, and My Chemical Romance lose to Rage by an extremely small margin.
