Where's the theme music?

You know those movies where everything is moving along smoothly and the musical score is light and airy, and suddenly you notice that the music starts getting darker? You can usually tell when the scary part is coming, and if you are like me, sometimes you even mute the television so the scary part is less frightening. Don't you wish it could be like that in real life? You could prepare for the scary parts if only you could hear the music. I am waiting for a call from someone right now, and I am seriously imagining the theme from Jaws. But, of course it may just be my overactive imagination. Someone please queue the theme music so I can get ready! Maybe I should put this paper I was editing in the freezer, a la Joey!
