Gotta go with the obvious here. "Black Sabbath." I used to play it on my radio show in college. Alone in the studio in a spooky gothic building, late at night. Unable to look away from that cover. Daring myself to play "it" without freaking myself out. Always did (both).
*shivers at the recollection.*
What is this that stands before me?
Figure in black which points at me
Turn around quick, and start to run
Find out I'm the chosen one
Big black shape with eyes of fire
Telling people their desire
Satan's sitting there, he's smiling
Watches those flames get higher and higher
Oh no, no, please God help me!
Is it the end, my friend?
Satan's coming 'round the bend
People running 'cause they're scared
The people better go and beware!
No, no, please, no!
