For a levelrank fixing tourney, one implementation would be as follows. Fix a division and let P be the set of players in that division. Let S be the collection of songs such that there does not exist a player in P who has AAA'ed it. For each song s in S, calculate A(s) where A(s) is the average of the ranks on s among the players in P. The round for that division will be the s in S that maximizes A(s).

tl;Dr the round song will be a file that everyone has a bad rank on (on average) excluding songs that someone has AAA'ed.

There would be some details I'd need to work out to balance things, but that's the gist. Such a format is subject to being "gamed" in the sense that people can manipulate their levelranks before/during the tournament, but we can just count that as being part of the meta.
