I don't intend to rain on anybody's parade and this is just a suggestion. A better, more democratic way to do this stripping business is to eliminate a song from a list only if it gets the maximum number of votes from all participants. For example: You have a list of 20 songs from the 90s. Somebody will then run 19 poll threads, one after another to eliminate 19 out of the 20 songs. The last song standing is the winner.
Or if you think, that's too many poll threads for one list clogging up the forum then... let all participants rank the 20 songs in order of preference and then post their lists. One person will then collate everything and determine the overall Top 20.
