Ok. This one was hard and I'm pretty sure I missed one or two. For what I did get, though, I think It's in the right order. I'll figure out the ones I missed tomorrow or if someone knows, they can tell me.

You put The Avalanche and The BQE before Seven Swans? Weird, I agree with your first two and last one though.

Mine:
Sufjan Stevens
Michigan>Illinois>Seven Swans>The Avalance>A Sun Came>The BQE>Enjoy Your Rabbit

and I'll do some more:

The Hold Steady:
Boys and Girls in America>Separation Sunday>Heaven Is Whenever>Almost Killed Me>Stay Positive

Tegan and Sara:
This Business Of Art>If It Was You>Sainthood>Under Feet Like Ours>The Con>So Jealous

and The Mountain Goats.
All Hail West Texas>Tallahassee>The Sunset Tree>Zopilote Machine>Sweden>Heretic Pride>We Shall All Be Healed>The Life Of The World To Come>Get Lonely>Ghana>The Hound Chronicles>The Coroner's Gambit>Hot Garden Stomp>Taboo VI: Homecoming>Full Force Galesburg>Hail and Farewell Gothenburg>Nothing For Juice
(the rest I don't want to put in the effort of going into)

Era Vulgaris>Self Titled>Lullabies to Paralyze>R>Songs for the Deaf

Not positive on the last two though.

It's really funny how people can have the exact opposite of your opinion regarding music. But I must say, I'm a big QOTSA fan and I really like all their albums. I do get bored with the self-titled one though, and that's why I put it last

That's just wrong. I haven't subjected myself to all of their more recent releases, but it's self-titled >>>>> everything else. What I own:

KoRn > Follow the Leader > Issues > Life Is Peachy

You know it's a great band when nobody can figure out just how good each of the albums are.

QOTSA:

Rated R > Songs for the Deaf > Era Vulvaris > Queens of the Stone Age > Lullabies to Paralyze

The only two I listen to consistently are the first two so the last three could be different three months from now...

Some others I've already seen listed:

The White Stripes:

Icky Thump > De Stijl > White Blood Cells > The White Stripes > Elephant > Get Behind Me Satan

Tool:

Aenima > Opiate > Lateralus > Undertow > 10,000 Days

And my two favorite bands:

Red Hot Chili Peppers:

Blood Sugar Sex Magik > Freaky Styley > Mother's Milk > The Uplift Mofo Party Plan > One Hot Minute > Californication > Red Hot Chili Peppers > By the Way > Stadium Arcadium

I feel like I have done that list twenty times (I prolly have).

Primus:

Frizzle Fry > Sailing the Seas of Cheese > Pork Soda > Antipop > Tales from the Punchbowl > The Brown Album

It's really Frizzle Fry/Seas of Cheese and everything else...

Mew

Frengers > No More Stories... > ..And The Glass Handed Kites > A Triumph For Man > Half The World Is Watching Me
