I think I can say this...it's probably the only U2 song left that I would have a problem with if it's left off of future concerts. That's how good I think it is.
It is, in my opinion, the second greatest U2 song ever. It is one of those songs that shows how good they all are at playing individually and feeding off of one another at the same time. It might not be one of the best representations of how well Bono can sing, but it certainly is one of the best representations of how well Bono can write lyrics.
5/10 just because it's hard for me to rate a U2 song lower than that. Boring and overplayed in concert. I pray they leave it off the setlist, at least for the show I get to!
