This album has got some pretty good songs (Mileena, Liu Kang, Baraka, Reptile, Kano), and also some bad ones, unfortunately (mainly Sub-Zero and Kung Lao).
My favorite is Reptile's theme, hands down. I had never heard of Skrillex before, but I'm certainly gonna search stuff about them after listening to this song. I's got an awesome beat, so sick, so fast, makes me wanna dance (which I actually did).
