Some of my favorite songs are not on my favorite albums.
Using the criteria that every song on it must still hold up for me, and making a distinction between concept albums and others, off the top of my head I guess I'd say:
Concept albums:
Pink Floyd:
The Wall
Animals
DSOTM (although it could be questioned whether this fits the concept album definition)
Eagles - Desperado
Others:
Elton John - Madman Across the Water
Steely Dan - Countdown to Ecstasy, The Royal Scam, Aja
Kansas - Leftoverture, Point of Know Return, Monolith
Jackson Browne - Late for the Sky, Running on Empty
Eagles - Hotel California
Dylan - HWY 61, Blood on the Tracks, Time out of Mind, Saved
Steve Earle - El Corazon, Jerusalem
