Music for the readers!
Short, concise description of the idea
Music plays (of the users choice) for the readers to listen to as they read their Livejournal.
Full description of the idea
You've all come across websites that plays music when you enter it and plays on as you continue to browse (look through) their website. My suggestion is that you can do that with your livejournal. The user can pick and choose a song to play when someone visits their livejournal and reads it. That way they are entertained with two sense the sense of sight and the sense of hearing.
