I've been scratching my head trying to find good creepy/tense music (I've the Silent Hill OSTs already) and can't seem to find any. Any instrumentals/sounds that creep you out or Dark Ambience (http://www.dreamstate.to/audio/captive.mp3) is deeply appreciated. (Sample of what Dark Ambience is, is within the link.)

Thanks in advance.

look for resident evil or devil may cry music, most of the songs have a dark and creepy tone.

^ I have DMC music, and I've downloaded several Resident Evil songs that have sound effects rather than a real track. -_-

The obvious answer here is nabbing the actual ambient pieces from silent hill, or stuff the extended scores or full game rips, soft piano and dark low tones, sounds right up your alley my friend.
