I voted 3, but if there were something between 3 and 4 I would have chosen that.
I really like the verses, but the chorus doesn't quite meet my expectations following those brilliant verses. Good single, but not great. I can feel it growing, however, which is a good sign, of course.
I really love it....I think this sort of tune sets U2 apart from other bands....like mysterious ways....lets face it Oasis/Killers/Kings of Leon could never make something this funky and outside their comfort zone! What I really like is that the band sound like they let loose on this song and enjoyed themselves.
