A Fanlisting is basically a list of people from all around the world who gather to show their support for a specific subject, i.e movies, books, songs, etc. When you join your name is listed on the "Fans" page and that's it. There is nothing else you need to do, no messages to post, no checking back regularly - all it is, is a list of fans. =)
This fanlisting is for the Tokio Hotel song 'Gegen meinen Willen' which you can find on their first album 'Schrei' and on the Re-release 'Schrei - So laut du kannst'.
