I like a large variety, mainly rock:
Queen, Muse, Kaiser chiefs, linkin park, panic at the disco, The Feeling, Avril Lavignei, Blink 182, Evanescence, Fall Out Boy, Gorillaz, Guns N' Roses, Gym Class Heroes, arctic monkeys, The Offspring, Snow Patrol, Tenacious D, LinkinPark, Paramore, My Chemical Romance, All American rejects, Coldplay, Greenday, Panic! At the Disco, Amy Winehouse Nirvana, Foo Fighters, Razorlight, Europe, Lady GaGa, D-ream.
I'm also, poised to book tickets to glastonbury 2011 (The UK's best music festival), its awesome, bigger and better than E3 if you can believe it lol (In my opinion).
So whats everyone else's musical preferences?
