Oh, this is all very difficult.
When I first listened to the first two clips, ABOY stood out immediately as a "guitar rocker," and I liked that. It had an AB guitar kind of feel to it, so I was in heaven. Not to mention the solo! The first listen of COBL wasn't as good...
But then I listened to it again. And again. Now I can't stop listenening to it! It's such an amazing song, it makes me cry whenever I hear the "Oh - you - look - so - BEAU - TI - FUL!" The only U2 songs that have ever made me cry are WTSHNN, WOWY, NYD, and One, so this is saying something. The lyrics are great, the music is great, EVERYTHING is great. When Edge sings the "ahhh" back-up towards the end after the "oooh" part, I get shivers down my spine.
So right now, COBL is winning, hands down.
