The sweet mix of apocalyptic songs was done by musician Chad Neidt, who has been featured here on The Feed a few times now for his upbeat and fun musical mashups, and who brings together a perfect mix-tape for the Mayan calendar prediction.

Watch John Hodgman give an "Apocalypse Survival 101" course in our video below from THNKR so you can be prepared for the worst.
