Every year since 2008, DJ Earworm has mashed up the 25 biggest songs of the year in his annual United States of Pop series. It's become a staple of the holiday season, as indicative December as Top 10 movie lists, Michael Buble and climate change denial.
Each video in the series is a brilliantly-blended fusion of the day's biggest pop stars, and if you do go back to 2008, you get a pretty good idea of how much things have changed already.
That's right, Leona Lewis, lots of Chris Brown, and Ray J doing a song with someone named Yung Berg. The pop world is fickle, people.
Want even more of these same songs? Us The Duo did their own medley of songs.
Unfortunately, it seems like "Everybody Knows Shit's Fucked" did not make the cut.
