This would be my ranking of the albums based on the songs ranking and a related simple scoring system (#1 gets 100 points, #100 gets 1)
The figures show total points, # of ranked songs, average score per ranked song, total # of songs in the album, average score per total # of songs.
Sorry for the table alignment, I don't know how to make it square..

Looking at the average score calculated on all songs, I&W clearly dominates, while ADTOE turns out to be at number 2, even though I would not consider it to be my 2nd favourite album..
SFAM is my 2nd favourite, because its "value" as an album is certainly higher than the sum of the individual songs...
