Nice thoughts Trolsk. My suggestion would be to allow people to vote for more than a top 5, since there weren't that many voters this year so more votes would allow for a statistically more meaningful chart. I agree that a top 10 would be good, in which people could leave the last few blank if they didn't want to nominate that many albums. Also having the scores range from 1 to 10 would be better than 1 to 5, since for example I felt that my no.5 album of the year deserved more than one fifth the credit of my no.1 album, and I expect a lot of people would agree.
edit: I don't mean to suggest that Moni didn't do a great job this time round, because she did, obviously.
