While I've liked many a U2 song, I've never been a fan. In 1987 I Still Haven't Found What I'm Looking For was released and struck a chord with me. It's a great track; it's held its own. But I find myself hating it now, possibly because I've realised that just maybe I won't ever find what I'm looking for. Not because I don't know, I do, but what I'm looking for changes so frequently. As an aside, one of the best U2 covers is Where The Streets Have No Name by the illustrious Pet Shop Boys.
