Those who think ABOY is filler - I'd like them to try and listen to the album without it. Apart from Vertigo it's the only fast, rocking song, and the album really needs it. As great as the album is it would be missing something without this song a lot more than it would without, say, Original of the Species or Crumbs from Your Table (good songs, but not all that integral to the whole). I agree the chorus isn't exactly great, but I think the intro is the best on the album, it's the only time Edge does a proper rock solo (and a nice one, too), and the it's got the heaviest riff U2 have done in a while. I love it.
