I just posted this over in the rankings thread. Time can change things, but I think this is where I'm at right now.
1. Achtung Baby
2. The Joshua Tree
3. Zooropa
4. TIE: UF/Pop
6. Boy
7. Rattle And Hum
8. SOI
9. War
10. October
11. ATYCLB
12. NLOTH
13. HTDAAB
Probably the most controversial things would be putting SOI above War and putting Boy that high.
War has some unassailable classics on it, and to be sure, I'd take New Year's Day or Sunday Bloody Sunday, maybe even Drowning Man, over anything on SOI, but I feel that SOI is a little more consistent front-to-back.
I just think Boy is one of the most cohesive, energetic, and exciting records in their catalog. They were so young and free of the weight of fame and legacy and record label expectations and being "U2" and all of that. They would never again sound that uninhibited.
Also, I feel like a lot of people are giving R&H the shaft. Of the nine studio tracks, they're mostly damn good, imo.
The top 5 haven't changed in a long time, and I'm not sure they will.
I feel like #8 is a fair balance between being enthusiastic about a new record while not disrespecting the classics that came before by displacing them for a record that isn't yet a week old.
