Your choices are a) The Killers b) Snow Patrol c) I don't care for either d) Coldplay rules! e) U2 called and wants their sound back.
I am going with Snow Patrol. Although the Killers have incredibly explosive and entertaining singles, Snow Patrol gives me a better depth of quality music. I know when I queue up a Snow Patrol album I will enjoy the entire experience. When I hear the first chords of pretty much any song it takes me someplace new. I can't explain it, except that it is an exceptional experience that few bands offer me.
But those are my thoughts. Let me know what you think of the Killers and Snow Patrol, or if you think we will even think of them 20 years from now.
