I got a few of these mp3s from Gamestop for buying/preordering the game & forgot about them. After listening to them & finding the rest on youtube, there's some good & some bad ones. Maybe it's because I heard Baraka's first (which I think is quite good) then getting completely disappointed with the one for Shao khan. Granted I was hoping that Shao Khan's piece on this cd would be layered with him taunting you, sadly not. But from what I've heard so far, it's pretty damn good on many of them, here's a few & the person who uploaded this also did tons of other MK music :).
  

Reptile, Liu Kang, Johnny Cage, and Mileena character themes are my favorite!

It's a shame that none of the "songs inspired by the warriors" were used in the actual game, although the reptile theme was used in the commercial

Eh, I'll take Chinese Ninja Warrior over this stuff any day. 

I prefer playing with the klassic music whenever I can. 101-101 I think is the kombat kode for it.

Baraka's theme is insane, LOVE IT!

I dig reptile's theme, it's as close to dubstep that I will ever get to without hating myself.

I think Goro's theme is the only one I like.
