Just Like In the Movies.
In a way it would be really cool to have a sound track follow you through life. If something bad was going to happen the music would get creepy sounding. So you then would have a choice, do I continue on to face "the music" or do I choose to find a direction where the music is much more to my liking. It would be like playing the "warmer, colder game" but with sound. Really be cool if you go swimming in the ocean. You would always know if a shark was coming around.
