Anybody familiar with the heavy metal group type o negative? On their album "world coming down" there is a very short track called sinus.A mere 53 seconds. But during the first 24 sec. You can hear what sounds like rattling chains and if you listen carefully a woman in the background laughing and screaming nooohohoho!! oh no!! The rest of the 53 sec. is the sound of somebody blowing their nose. YUCK!! Hense the name of the track I guess. You dont have to get the whole album to hear it, if you go to ITUNES you can download sinus for a buck.
