Not a very imaginative choice for today, but so be it. It is difficult to imagine that there was a time when U2 was struggling for success, but they actually had to wait for their fourth album to make it big. Their first album (Boy) was a good collection of straightforward rock songs, but it gave no indication yet of things to come. The second album (October) was a bit mixed, with some questionable tracks, and some great songs, in particular the title song. Their third album (War) was their artistic breakthrough, helped to a large extent by the success of the single New year's day, the best U2 song of all time - in my humble opinion of course.
Art Rock score: 10/10 (brilliant masterpiece, one of 200 best songs of all time)
