In each poll you should vote for 3 of your favorite songs from 2012.
Because there's a limitation to how many options you can have of a poll, there will be 6 of them. When these 6 polls have finished we'll have a final poll with our top 18 of 2012 in which you, again, will be allowed to vote for 3 of your favorites.
The results will then be edited into a video and posted on youtube (and here) for all of us ranking-freaks to watch. : D
