Mine would be pretty similar to the first page, adding in
In Rainbows
one of the various Foos records
Mad Season - MB20
By The Way - RHCP
Leave a Whisper - Shinedown
and then ABiii or Blackbird
and of course BGWTB
Just a couple that come to mind:

Radiohead - In Rainbows/Amnesiac
Pearl Jam - Riot Act
QotSA - Songs for the Deaf
Oceansize - Effloresce
Beck - Modern Guilt
Sun Kil Moon - Ghosts of the Great Highway
Patrick Watson - Close to Paradise/Wooden Arms
At The Drive-in - Relationship of Command
Wilco - A Ghost Is Born
Justice - Cross
Arctic Monkeys - Humbug

And I know we're all forgetting tons and tons of cool shit.

Edit: Like Broken Social Scene's You Forget It In People, which is spectacular.

Alphabetically top ten, one submission only from each band.

Black Rebel Motorcycle Club - Howl, 2005
Clutch - Robot Hive/Exodus 2005
Down - Down II: A Bustle in Your Hedgerow, 2002
Drive-By Truckers - The Dirty South, 2004

Lucero - Nobody's Darlings, 2005
Maylene & the Sons of Disaster - II, 2007
Murder by Death - Who Will Survive and What Will Be Left Of Them, 2003
Pearl Jam - Lost Dogs, 2003
Toadies - Hell Below/Stars Above, 2001

as far as what I still listen to the most today.

Early 2000's I listened to a lot more Nu Metal, Heavy Metal, and modern rock than I do today.
"Pain or damage don't end the world nor despair, nor fuckin' beatings. The world ends when you're dead, until then you have more punishment in store. Stand it like a man, and give some back."
Not in any sort of order, just some of the great albums that I've consistently listened to over the years.

Porcupine Tree - In Absentia, Fear Of A Blank Planet
Alter Bridge - Blackbird
Transatlantic - Bridge Across Forever
Rush - Vapor Trails
Opeth - Damnation
Pain Of Salvation - Remedy Lane
Dream Theater - Six Degrees Of Inner Turbulence
Nightwish - Once, Century Child
Silverchair - Diorama
Shinedown - Leave A Whisper
For me, in no particular order, it'd be (with just one album per band):

Muse - Black Holes and Revelations
QotSA - Songs for the Deaf
Less Than Jake - Anthem
Mew - No More Stories...
Porcupine Tree - Fear of a Blank Planet
Feeder - Echo Park
Enter Shikari - Take to the Skies
Dredg - Leitmotif (I know it was indie released in '98 but I got the re-release from '01)
Coldplay - A Rush of Blood To The Head
Robbie Williams - Escapology
Gorillaz - Gorillaz
Karnivool - Sound Awake
Radiohead - In Rainbows
The Killers - Sam's Town
Morrissey - Ringleader Of The Tormentors
Gorillaz - Demon Days
The Last Shadow Puppets - The Age Of The Understatement
Muse - Black Holes And Revelations
Arcade Fire - Funeral
Paul McCartney - Chaos And Creation In The Backyard
Coldplay - A Rush Of Blood To The Head

Of course only one entry per band, but if I had more, I would definetely add Hail To The Thief, Amnesiac and Kid A by Radiohead!
Just cause you feel it, doesn't mean it's there.
