What's your favorite game theme music?

[Vitis]

My favorite video game musical composition is Ryu's Theme from the Street Fighter II and Street Fighter Alpha series. Ryu's Theme: https://www.youtube.com/watch?v=z2F59qX-gO0
Yoko Shimomura composed Ryu's Theme as well as most of the music for the original Street Fighter II. http://en.wikipedia.org/wiki/Yoko_Shimomura
She is a brilliant musician and one of the most prolific video game music composers in history.

So what's your favorite video game musical composition?
