Found this on a reading & leeds forum to do with main stage acts, but it can easily be transferred to something like, say, radiohead albums (an admittedly simple one).

Basically, everybody has a turn per day, and get to add and take away 3 points each turn (so the overall points balance remains the same). You add points to an option when you like it, and take points away when you dislike it. Basically, each option has 24 points. You can spread your points about options, as long as you add 3 and take 3 away. When an option reaches 0 points, it is eliminated. The last one standing wins. So here is mine:

Pablo Honey 24
The Bends 24
OK Computer 24
Kid A 24
Amnesiac 24-2= 22
Hail To The Thief 24
In Rainbows 24+2= 26
The King of Limbs 24-1= 23

Best to make it obvious which ones youve given points to or taken away from, otherwise from experience people misread things and get confused.

So yeah, there we go.
