Actually, I'll make a list using more of that approach (though I suppose it'll still be somewhat of a personal list), because I know for certain not everyone would dig things like Hammock, Eluvium, Eno and such.
Kind of Blue - Miles Davis (and co.)
What's Going On - Marvin ***e
Bridge Over Troubled Waters - Simon and Garfunkel
Blue - Joni Mitchell
Dark Side of the Moon - Pink Floyd
Sgt. Peppers - The Beatles (Abbey Road would work fine as well)
OK Computer - Radiohead *
Blues Breakers with Eric Clapton - John Mayall and the Blues Breakers
Led Zeppelin - Led Zeppelin (part of me wants to say Led Zeppelin II)
( ) - Sigur R
