Listening Discussion 9: Film and Video Game Music

I would like each of you to choose an example of film or video game music that you like, and discuss the following things:

What, if any, influences do you hear from the music we have covered in class so far? 
Do you think this is source music or underscoring? Why? 
What is the difference between source music and underscoring?
