What is a fanlisting?

Taken from TFL.Org:
A fanlisting is simply an online listing of fans of a subject such as a TV show, actor or musician that is created by an individual and open for fans from around the world to join. There are no costs, and the only requirements to join are your name, country and e-mail address. Fanlistings do not have to be large sites (although some are) - they are just a place where you can have your name listed alog with other fans of the same subject.

The Theatrhythm games are based on the Final Fantasy series collection of music released for the Nintendo 3DS system. There is an imbalance of harmony and chaos in the world, so it is up to whatever collection of heroes you choose to have in your party to collect something called rhythmia to help destroy Chaos and restore harmony to the world.
