Love Interruption by Jack White could very well be Macbeth's theme song.
Who done it?
Piece of Art!
I believe this art relates to Macbeth. The skeleton would be him because he is dead already on this inside but continues to murder others just so he can be above but in the end they all are truly dead. When Macbeth is freaking out and hallucinating, he is shown best as being a goner and a ruined human with nothing left but the framework (skeleton) of a human being. But even as he is dead, he continues to kill until he is stopped.
