Ipod discoveries

An idea I had was to have an ipod that a character comes across on the street, on the floor. They put the headphones in and select a song, for example 'London Calling - The Clash' the character is then transported to Buckingham Palace or Trafalgar Square. Confused, they select a different song and so on, then eventually they select 'YMCA - The Village People' and end up in pitch black with disco lights (in a gay bar) and the character frantically tries to change the song over before 'the village people' turn up ! We liked the idea but decided it could be quite hard to do finding different locations and so on also we felt the challenge of doing a comedy and decided perhaps not to attempt one yet at this early stage.
