This is a truly magnificent theme for a certain comrade of mine. 

El MunozScyther

snap yo snow mountain

There are so many lives
his music saved
Lost souls rescued
by the metal that he gave

He turned the world upside down
with something never heard
A voice forged by fire
it made the planet burn

He's gone back to his home
a spirit in the sky
Forever the Prince of Darkness
Forever alive

He rocked our world
it will never be the same
He is the reason
for metal on the brain

Followed by curses
always fighting with the pain
He gave us all a ride
on the crazy train

There are so many lives
his music saved
Lost souls rescued
by the metal that he gave

The six string warriors by his side
made riffs that paved the way
They sounded so strong had so much force 
it made us want to play

He's gone back to his home
a spirit in the sky
Forever the Prince of Darkness
Forever alive

He's gone he's finally home
his palace in the sky
Forever the Prince of Darkness
Forever alive

The Prince Of Darkness

Watch out for skeletons, one could already be inside you.
