A dance with the devil ( acceptance)

I've heard your cry
And I've thought it through
When you die
I'll take your soul from you

I've accepted your request
And its by mere chance
I am the best
So, let us dance

But first you must sign
And to sign you must bleed
Then your soul will be mine
And we can proceed

To the lake of fire
That is where it will be done
In front of chorus and choir
Your soul will be won
