They need to acquire the rights of Mk techno syndrome and use it as the games official theme song. There was no theme song in mk9.

Heres what i would do mix both these songs and always play it whenever a moment of hope comes up throughout storyline.

2pac - ambitions as a ridah

http://www.youtube.com/watch?v=UYf7q7bpY-0

A ridah is someone who loves to go to war is down for pretty much anything. Boadicea was a queen who led an uprising against the roman empire, so she can be called a ridah. So this song should be called ambitions as boadicea as they both go hand in hand. Or you can keep them apart so play ambitions as a ridah whenever there is someone who is owning the others. And play Boadicea whenever there's a moment of fear.
