Okay, I'm going to give this a try. It's extremely tough because I love every album, so my rankings tend to change on a weekly basis. Aside from my top five, everything else might as well be tied for sixth but I'll attempt to put together a list based on my 2012 preferences.
1. The Joshua Tree
2. Achtung Baby
3. The Unforgettable Fire
6. How to Dismantle an Atomic Bomb
7. No Line on the Horizon
10. Rattle and Hum
11. All That You Can't Leave Behind
