IT'S FINALLY HERE! DJ Earworm has shared his annual epic mash-up of the year's biggest and best songs: "United State of Pop 2014 (Do What You Wanna Do)."

Every year since 2007, DJ Earworm has combined the year's hottest tunes and combined them all into one amazing song, and this year's mash-up may just be the best one yet! "United States of Pop 2014 (Do What You Wanna Do)" features tracks like DJ Snake & Lil Jon's "Turn Down For What," Iggy Azalea & Charli XCX's "Fancy," Jason Derulo's "Talk Dirty," Taylor Swift's "Shake It Off" ... even "Let It Go!" 

This year's "United States of Pop" is a bit different than previous years. DJ Earworm tells Billboard that 2014 was "dominated by these slow, ponderous songs like 'Say Something' and 'All Of Me,' and then swaggering hip-hop songs like 'Turn Down For What,' 'Talk Dirty,' and 'Black Widow.' Then you have totally uptempo songs like 'Happy' and 'Shake It Off,' too. It's a little bit more diverse, and definitely softer than it’s been."

Check out DJ Earworm's "United States of Pop 2014 (Do What You Wanna Do)" below!
