Hit the jump for some interesting facts about the song.
Quite possibly the first metal lullaby, it is probably the band's best known song. The breakdown brilliantly utilizes that 'Now I Lay Me Down to Sleep' bedtime prayer in such a way as to add to the scary movie aspect of the song. Favorite part is the twisted lullaby part in the breakdown, "Hush little baby don't say a word, and never mind that noise you heard. It's just the beasts under your bed, in your closet, in your head".
Fun fact #1: The song was used by NASA mission control to wake up space shuttle astronauts.
Fun fact #2: The song made headlines during the 2003 invasion of Iraq after it became known that uncooperative prisoners were exposed to the song for extended periods by American interrogators. According to United States Psychological Operations, the intention was to "break a prisoner's resistance by playing music that was culturally offensive to them".
