I missed the millennial roundup in '99, opting to spend that weekend getting high in montreal. Apparently, that was a less self-destructive road taken, if your memories of the meeting conjured up images of this.

Um, so you and Brian came up with complex contest rules and statistical formulas when you were drunk? Going to have to raise my game next time out: slurring just won't cut it.

Like your idea. Agree that it's preferable to a 'here's why i chose radiohead's ____', a superfluous undertaking at this point, surely. We'll just have to come up with a process that everyone can follow, throughout various degrees of sobriety.

Since we're talking about weighted values, let me say that I'm struggling a bit with my analysis of the lists. Would that I had paid more attention in 2nd year Statistics, a course for which I celebrated wildly upon barely receiving a passing grade, but have now retained zero knowledge.
Maybe one of you can assist.

I went ahead and ranked each list in order, then decided that the #1 entry on each list would be assigned the highest possible points in the ranking (i.e. if it was #1 of 100 entries, then it would be assigned 100, if #2, then 99, if #3, then 98, etc.), then divided the assigned number by the highest ranking and multiplied by 100. Bear with me. So the #1 entry ends up being 100.0, and #2 99.0, etc. It therefore takes into account those lists that are ordered out of say, 50, or 75 or 45.
I then added up the scores for those that appeared on the list more than once and then divided this number by 6 (the total number of lists). I then ranked these scores to come up with the resulting list of our top 30 of the 2000s, by consensus:

1) Arcade Fire - Funeral
2) Decemberists - Picaresque
3) Badly Drawn Boy - Hour of the Bewilderbeast
4) Sufjan - Illinoise
5) Arcade Fire - Neon Bible
6) Strokes - IsthisIt?
7) Wilco - Yankee Hotel Foxtrot
8) Broken Social Scene - youforgotit
9) Calexico - Feast of Wire
10) Strokes - Room on Fire
11) Beck - Seachange
12) Radiohead - In Rainbows
13) Tourist - St. Germain
14) Suba - Sao Paolo Confessions
15) The Shins - Chutes Too Narrow
16) Band of Horses - EverythingAllthetime
17) Radiohead Kid A
18) Koop - Waltz for Koop
19) Flaming Lips -yoshimi
20) TV on the Radio - Cookie Mtn
21) Stars -Set Yourself on Fire
22) Sigur Ros - Takk
23) The Microphones - The Glow pt.2
24) The New Pornographers - The Electric Version
25) Madvillian - Madvillainy
26) Elliot Smith - Basement Hill
27) My Morning Jacket - Z
28) Grandaddy - Sophware Slump
29) Kos - joyful rebellion
30) Neko Case - Fox Confessor Brings the Flood

Let me know what I've done wrong (specific to above).
