DJ Earworm’s end of the year mashup is out, and it's epic! He's the guy who takes the 25 biggest songs of the year and combines them into one song.

This year’s “United States of Pop” remix is called "Do What You Wanna Do," and features “Fancy,” “Shake It Off,” “All About That Bass,” “Rude,” “Stay With Me” and more. And, even though it's a bit melancholy and not as upbeat as last year's, it's still pretty sweet
