I think that Mortal Kombat 3 should have specific music for certain characters and fights. They should ask the fans what kind of battles they would want to see. These are mine:

QUAN-CHI
A kind of tribal war music fits Quan-Chi in my opinion. It would be cool seeing how he has all of those tattoos and stuff. To show the audience his true strength he should fight against a pack of centaurs or shokan. Possibility for KINTARO??

JAX
Some kind of rap like DMX or someone really hard. Jax needs to have the biggest fights like going up against someone like Drahmin, Moloch or maybe against Reptile.

SEKTOR
Definitely techno music. He should obviously go up against Sub-Zero in a final battle or have a few minor fights with people like Sonya, Johnny Cage or Kung Lao.

BARAKA
Seeing how vicious he is Baraka should have some kind of heavy metal with lots of screaming and stuff. I would like to see him have a fight with someone equally as vicious like Reptile or Kabal.

SUB-ZERO/SCORPION
This should be a major battle in the movie that will make the audience scream. I think that the music should be orchestral kind of like in Star Wars: Episode 1 with Darth Maul. They should have at least two fights, one in the Netherrealm and another in a forest or something.
