Heavy steps were taken from Will O' the Wisp Nightmare and derived into singles by Arch0wl (Nightmare is a much harder double mode, and surprisingly, the nightmare has much more notes than the single Crazy mode does)

Will O' the Wisp lyrics:

Take it outside 

Have you seen the actual reality of a monsters cry? 
Or only an illusion? 
The product of a tortured brain... 
Sucking the hallucinitory acid into the system... 


The "Will O' The Wisp" song refers to if the legendary Wisp was real, people would've done experiments on it, and later on, the Wisp is in suffering and in torture.. listen to the very end.. it sounds like a whimper... and while he's saying "Have you seen the actual reality" etc etc, that's the Wisp's cry... "Take it outside" refers to them getting rid of the Wisp.

(thanks to some research of myself and some others trying to find out the lyrics to it on the pumpxtreme.net forums)
