How about a new audio game to play alongside the picture game?
Post a tune that has some connection to the previous track posted. For instance, if I posted Call The Shots by Girls Aloud the next person might post Shoot That Poison Arrow by ABC (the link being 'Shots' and 'Shoot') and then the following post could be ABC by The Jackson 5 (the link being quite obvious), and then it could be Different for Girls by Joe Jackson that could go into The Show by Girls Aloud and so on.
The connections can be based on anything. It could be with song titles, artists names, appearing on the same film soundtrack, used to advertise the same product, former bandmates/collaborators...anything. The only rules are that there has to be a tangilble connection and you have to say what that connection is.
This piece of music appears in the film Plunkett & Macleane, starring Robert Carlyle and Jonny Lee Miller. As this is the first track there's no actual connection to anything. I just really like this piece of music.
