(I can do this post now they've sorted out the copyright issues!)
I've followed U2 for some 25 years now, since watching 'Live at Red Rocks' at boarding school, and buying Under a Blood Red Sky. They've gone through a few changes of style since then... It would be fair to say that I like just about everything they've ever done; that is, if I had to make a list of 'U2 songs I don't like' I probably wouldn't need more than one hand to list them on.
#10 Who's gonna ride your wild horses?
#7 All I want is you
#6 A sort of homecoming
#5 I still haven't found what I'm looking for
#4 Sometimes you can't make it on your own
#3 Miss Sarajevo
As for albums, I would just about choose Achtung Baby as my favourite, with either the first two or Zooropa being the ones I listen to least. I think the last three albums are all excellent.
BTW whilst researching for this post I came across this, which was useful.
