18. 'Native Son'
U2 have proved that it's possible to over-think a song and screw it up. Their 2004 song "Vertigo" was a big hit, but many fans prefers the tune in its original incarnation as "Native Son." It's not glossy, still has some rough corners and probably wouldn't have worked in an iPod commercial. The good news is they put it out so fans can compare the two.
