I know nothing of this.  I started it when my volume was off and decided to watch it without sound.  I found it disturbing and extremely dark although I believe I perceived the meaning.  Don’t know if I’ll rewatch it with sound or not…

It's just music. And there is more than one... five of these, I think.

I have not studied them or anything.  But I have had a number of clients reference them over the years. I just wondered how widespread these were and what people thought of them.
