Here's a couple of haunting songs I thought I should drop in here.
Ennio Morricone - Man with a Harmonica (death rattle)
Bernard Hermann - Twisted Nerve
Just as a side note, I just re-downloaded the entire life work of Ennio Morricone and am planning on uploading it to my iPhone, in phases as there's quite a bit to it. It's going to be my week's soundtrack, to listen to on the commute to and from work, as well as at work if I don't have too much editing or concentration work. Do you also find music distracting when you have a lot of "concentration" or "mind-exhausting" work?
