From the YouTube description:
The Decline by Punk band NOFX is all about the Government brainwashing the people and how this has lead to the breakdown of society, short description, it's a lot deeper than that. I'll leave a link below. So anyway, a friend in a NOFX Facebook group suggested that someone should play The Decline over Donald Trump's inauguration, so I did. It was just a joke at first but I can see that a lot of people are relating to this, so thank you.
