For anyone that cares to read this, the song portrayed in this picture is supposed to be unplayable, with dumb **** thrown in everywhere like placing a fish on your head and banging a triangle at times. Some people actually did it on youtube.
There's also a video going around claiming to be the 'Death Waltz' performed by John Stump, but has nothing to do with the real song. It's actually a piano cover he created for a popular anime song.

You're welcome.
