I discovered U2 only in the past few years, but I really love most of the stuff I've heard. I can't choose just one song though...I love Desire, In A Little While, Mysterious Ways, and With or Without You. I haven't purchased a CD in ages, but I will eventually get my lazy butt to a store and buy a couple of theirs. They are coming in concert sometime this year, but I couldn't find anyone to go with
