I should have never listened to NIN, but I have; too much. It started with Quake, then a neighbor gifted me a CD of Pretty Hate Machine and I followed it with Broken and The Downward Spiral, which then was the path I went myself.
The Quake soundtrack was what got me too. Sorry to hear that. Music certainly is a powerful modulator of the psyche. It can be devastating like a drug if young vulnerable and unprepared.
