Using only 3 songs - yeh, it's my game so they're the rules if you're gonna play - define U2
Me?
Pride - power passion and it has a strong 'message'
ISHFWILF - their 'faith' and all round brilliant song construction and musicianship
One - perfect song both loved and envied by other artists - the original is just sublime pure genius
For me, the extraordinary moments are when the songs are played live and so I would say these three embody that emotional pull above others...close call for WOWY, mind!
