Agreed. I'm always impressed with the production quality of his videos, he clearly spends a lot of time on them. He even has a google doc linked in the description to all the songs he uses in each video.
That's probably because in every Youtube video ever, there's always someone asking what's the song in the background. I think it should be recognized as law akin to Godwin's law, the Darud Sandstorm's law.
I think this might be the minting of an eponymous law, or at the very least, one I will attribute to you in the future.
