URGENT song request

hi. theres one song in hitman contracts i just can't find....... anywhere!!!!
it plays in the trailer where 47 stalks a fat old guy and finally shoots him in his limo, it also plays in several parts during the game when a hit is performed cleanly, and also in the cutscene in the last level where the swat guys shoot tear gas into his room. it's my favorite song in the game and one of the best songs in video games today, so any info on this track would be much appreciated!
