Well U2 doesn't come close to The Beatles, but by now U2 certainly is my 2nd favorite band.
I became a fan when they were in the news all the time during the Vertigo tour, unfortunately that was too late to still get tickets, plus we were going on holiday anyway the day they were playing in holland, and i wasn't a huge fan yet.
Sunday Bloody Sunday was probably my favorite song ever when i just discovered them. Then i saw the Boston concert, and i thought it was pretty amazing. But then, then i saw the Slane Castle concert on DVD, but it was that tv special, with only a couple of songs. I got the dvd as fast as i could, what a concert, what a live band...
By now i have all albums, and most live dvd's, including Red Rocks. In the beginning i liked Pop, but now i'm not a huge fan of it, probably their weakest work to be honest, Last night on earth would be my favorite song, and Mofo live is amazing. However i think Pop is their least darkest album, it makes me think of a sunny landscape.
I personally think TJT is their best album, and i really love the B sides as well. Now i also discovered the song Zooropa, i never actually listened to that song, but wow, what a song.
