I'm actually a U2 Fan since the age of 10. My favourite Album is War. My favo' song is The Unforgettable Fire and I think I heard nothing but U2 throughout my youth.
I know every single song, I know the best completely out of the back of my head, know every lyrics of those songs, know the details and still I think I'm not the maximum U2 Fan.
U2 inspired me. It's music that inspires me. And now, I'm listenening a lot to Coldplay. I thank god for Coldplay because, in my opinion, it's better to be a damn ultra fan of 2 bands than of one, or else you might encounter the day that you don't like anything at all. Balance, that's what it's all about.
And yes, How to Dismantle an Atomic Bomb is one of the best. War, is, in my opionion, their best.
U2 - Seconds!
