ahh, U2, my first concert ever, 1984 Radio citymusic Hall, Unforgettable Fire tour......great times Other fans have given you good advice...to simplify or reiterate...... to me must haves Under A Blood Red Sky......a good live version of earlier songs War Unforgettable Fire Joshua Tree Achtung...Baby To me those represent the core of all of the best U2 songs.......though I dig most of it right up until the last album....... admittedly the more recent stuff has been less than stellar from start to finish than some of thoseI listed above, but they still have some really good songs As you said there's a ton of greatest hits/compilations out there, you really can't go wrong with any of them....it depends largely on what "U2" you like best..the U2 18 and best of 80's and 90's as mentioned above are good places to start as well
