I don't know if we're supposed to PM it? But I didn't see that, so I'm just putting it here. Kinda lame/predictable choices. I cut out a lot of jazz albums and VU, because I'd be lying if I said I liked them more. And I wanted to keep it down to 10--it's hard enough to decide on that as it is. (And yeah, I hate Beefheart.)

1. The Beatles – Revolver
2. Tim Buckley – Happy Sad
3. The Beatles – Magical Mystery Tour
4. Thelonious Monk – Monk’s Dream
5. The Doors – The Doors
6. The Beatles – Rubber Soul
7. Van Morrisson – Astral Weeks
8. Jefferson Airplane – Volunteers
9. Crosby, Stills & Nash – s/t
10. Led Zeppelin – II

There's some serious lack of love for Magical Mystery Tour in this thread. This is my rushed list:

1. Magical Mystery Tour - The Beatles
2. Pet Sounds - The Beach Boys
3. Sgt. Pepper's - The Beatles
4. Odyssey & Oracle - The Zombies
5. The Beatles (White Album) - The Beatles
6. The Doors - The Doors
7. The Velvet Underground and Nico - VU & Nico
8. Abbey Road - The Beatles
9. Are You Experienced - Jimi Hendrix Experience
10. Smiley Smile - The Beach Boys
11. Revolver - The Beatles
12. Song Cycle - Van Dyke Parks
13. Waiting For the Sun - The Doors

23. Crosby, Still & Nash - Crosby, Still & Nash
24. We're Only In It For The Money - The Mothers of Invention
25. Incense and Peppermints - Strawberry Alarm Clock

Magical Mystery Tour was my favorite for a really long time. But Revolver passed it up recently, so I'm glad someone put it at the top.

It almost makes up for Incense & Peppermints making the list. :p
