Dj Earworm is back with his annual mashup of the biggest hits of the year! "The United States of Pop 2017" features the hottest songs of 2017.

See if you can recognize these tunes you hear on Z-107.3, from Ed Sheeran, Bruno Mars, Camilla Cabello, Chainsmokers, Post Malone, and of course no end of the year re-cap would be complete without "Despacito."

Be sure to keep your radio locked on the Z, for American Top 40's Best of 2017 Countdown, coming soon! Till then, take look back at some of Dj Earworm's previous year end mashups!
