SCP-012 song (Bad Composition)

Well what's behind this door
It's an old musical score
Though it are not my affaires
Well let's go down these stairs
I hear a very weird song
Going in there might be wrong
And it is not what we think
It's blood not berry dye ink

Advised by 035
Can this really save my life?
You should use it as a map
But that's certainly a trap
And if you do not resist
Then you will cut your own wrist
You might finish it perhaps
Go on until you collapse

It's a bad composition
Demanding for completion
It will try to control you
As it did with other victims too
