For any of you Diablo / II fans who haven't heard the mp3, it's sung to the
tune of Frosty the Snowman:

Nasty Diablo, has a dark and brooding soul.
With a dire plan and a hateful man, domination is my goal.
Nasty Diablo, is a fairy tale they say.
With a brimstone smell, I was up from hell to claim the world one day.
There must have been some magic in that old soul stone they found.
For when they placed it in my head, I was trapped far underground!
Nasty Diablo, hidden for a thousand years.
The Horadrim say I`ll return one day preying on your mortal fears.
Nasty Diablo, was released and headed east.
Where I sought to find two more of my kind, so the three could be unleashed.
He let them through the streets of town and right down into hell.
We only paused a moment when we battled Tyrael.
Nasty Diablo, made a final stand that day.
But I waved goodbye saying don`t you cry I`ll be back again someday.
