@jazgalaxy: Kinda late to this thread but there's some nice foreshadowing in the lyrics of Girl's Just Wanna Have Fun, even if they're not in the instrumental in-game version:
"Some boys take a beautiful girl
And hide her away from the rest of the world
I want to be the one to walk in the sun
Oh girls they want to have fun"
Not so much "foreshadowing" as a nice description of Elizabeth as the game progresses.
