Actually instead of a theme song I'd quite like to have all of the sounds from Zelda in life, such as unlocking and opening doors, opening containers, succeeding in things, new items and especially when travelling through time between my childhood and adolescence.
Devil May Cry 3-Now You've Really Crossed The Line. Even though that song can get old after playing DMC over and over and then downloading the song and listening to it over and over.
"Girls with Guns", by Tommy Shaw... I was surprised I actually enjoyed the song so much, that it became a favourite of mine... besides, this is the kind of girlfriend I'd be, lol... dangerous. >:)
