Music is an interesting topic. what I generally like depends on the setting and whom I'm around. I've often thought that your favorite and most intimate favorites though would be if you were isolated by yourself forever.

My 3 choices would be Dark Side of the Moon, Beggar's Banquet, & Exile on Main Street. (yeah, I'm a Stones fan)

However I would be sorely missing :

Zeppelin's "The Rover" , "Thank You" & "Bring it on Home". plus several others from Zep

Jimmy Buffet's " A Pirate Looks at 40"

Willie Nelson's version of "Always on my Mind", Johnny Cash's " Sunday Morning Sidewalk"

Elvis Presley's "American Trilogy" and his cover of "I did it My Way"
