"It's a grey goo of the average of every concept picked up from the concept of the song."

You just described 90% of todays music videos made by humans.

Even the worst music videos I have seen aren’t as incoherent as this mess.

This is actually mostly down to constraints: even if you suck you will suck in some coherent consistent way that will give your music videos more structure than this mess.

Those videos are just nihilistic despair.
