Sound of Satan!

I read this article online about the U.S military using Metallica's "Enter Sandman" as a torture device on one of Sept.11th hijacker, Mohammed al-Qahtani during his interrogation! That's funny… what's funnier is that it says it actually brought him to tears! …I wonder why, was it cos he thought Metallica played badly, or his fanatic ears feared the "immortal punishment" for hearing the sound of Satan?!
Okay now seriously, Al-Qahtani was surely scared to death of being captured, and the music was not soothing for once!, but why pick Metallica?

I played "Enter Sandman" found on 'tallica's "The Black Album", and listened to it like the first time…yeah, Ulrich's drum at the intro could really get on your nerves when you're scared, it's almost like a warning that something is coming so 'get ready'!
The lyrics are powerful, but I doubt the guy, probably lacking knowledge of proper English, was concentrating to what Hetfield was singing!

Personally, I don't think Metallica is scary. Metallica is inspiring, powerful, heavy-but not my pick to scare anyone. To play the "sound of Satan", they should put on something like Dark Funeral or Cannibal Corpse. That could freak out anyone without any pressure of interrogation!
