Top 40 albums, take two

I've thought it over and realize that I should just have some guidelines:

1. 1 album per band (hard to do w/r to my favorite bands but I'll give it a go)
2. No "Greatest Hits" albums
3. Live albums are ok if they are really good and distinct as live albums (you'll see my example below)
4. Soundtracks are ok (but I don't think I can have more than 1 on my list, absent special circumstances)

So, I want to further define what the list means. It is the 40 albums most important to me. Not necessarily the 40 most "important" albums I own ( as in important in a global sense), but the albums that have been most important to me historically. This means that an album may be less important to me now, but if it was at some point really important to me or I really really loved it, it at least merits consideration. Also, when choosing the one album from a certain band to include, I will include my favorite one, not necessarily the one I think might generally be considered the "best". Ok, here goes:

Nevermind - Nirvana
OK Computer - Radiohead
The Process of Belief - Bad Religion
Pet Sounds - The Beach Boys
Paul's Boutique - The Beastie Boys
Abbey Road - The Beatles
Odelay - Beck
London Calling - The Clash
Take Five - Dave Brubeck
Under the Table and Dreaming - Dave Matthews Band
Yoshimi Battles the Pink Robots - The Flaming Lips
Welcome Interstate Managers - Fountains of Wayne
Franz Ferdinand - Franz Ferdinand
American Idiot - Green Day
Appetite for Destruction - Guns N' Roses
Lost and Gone Forever - Guster
Turn on the Bright Lights - Interpol
Utonian Automatic - Isotope 217
Nothing's Shocking - Jane's Addiction
Blue Train - John Coltrane
Houses of The Holy - Led Zeppelin
What's Goin' On - Marvin Gaye
Bitches Brew - Miles Davis
Double Nickels on the Dime - The Minutemen
Signals, Calls & Marches - Mission of Burma
Slanted & Enchanted - Pavement
Vs. - Pearl Jam
Dark Side of the Moon - Pink Floyd
Surfer Rosa - The Pixies
It Takes a Nation of Millions to Hold us Back - Public Enemy
Pulp Fiction - Soundtrack
Document - REM
Californication - Red Hot Chili Peppers
When I Woke - Rusted Root
Melon Collie and the Infinite Sadness - Smashing Pumpkins
Superunknown - Soundgarden
Stop Making Sense - Talking Heads
Joshua Tree - U2
White Blood Cells - The White Stripes
Yankee Hotel Foxtrot - Wilco

So, now I've gotten it to 40. My next task will be to think about whether I can put it into some order, or maybe even say something about each album.
