This is a very catchy song. Death and Taxes is a game where you can go as a Grim Reaper. It's your job to decide who lives and who dies because nothing is certain but death and taxes. You have a boss that you report to, and he has a cat. You get paid each day and when you can buy stuff in the store like a calendar to keep track of the days. There is also a bar you can go to, to talk to the barkeep and other patrons.  There's a lot of paperwork to do and it can be tedius but whoever you choose to live, or die will have some kind of consequences. Your boss will give you instructions and you can choose to do what he tells you or to ignore some of the instructions or all of the instructions. You have a phone that gives you updates to what is going on outside. There are multiple endings to this game so figuring out how to play will help you get the ending you want. 

"In this world, nothing is certain except death and taxes." Benjamin Franklin.
