But it also is, that's the thing! The song can be understood as being about singing; just like Breathe... and actually a lot of songs can be 'read' that way on this album..hmm....
That's a good point... the interpretation I generally follow is what Lanois and Bono talk about, essentially where lovers creating an "ultimate relationship" by working not for themselves, but for God, the universe, or something greater... whatever you want to call it. There are a bunch of perfectly valid interpretations of the song... it just bugs me when people attack the song because Bono is being OMG ARROGANT in that line without looking into the implications of the line!
