This is a pretty emotional game in which people are forced to do something they are sometimes reluctant to do: publicly declare that they really believe in something, and then have that stance judged by others.  Each participant chooses an entire piece of recorded music that fits the requirements of that particular game and introduces it before it is played for the group.  This introduction can (and should) include an impassioned argument/plea for that selection’s acceptance and votes.  Ironic selections are strongly discouraged.  Because all the pieces must be heard by everyone at one time, there is usually a rule requiring them to be fairly short, but this can change when the schedule can accommodate a longer game.
