Between Billie Eilish [1]'s breakout and Billy Ray Cyrus's unexpected comeback, it's been a wild year for music. As part of his annual "United State of Pop" mashup series, DJ Earworm just released a catchy mix of the year's top songs, featuring Post Malone [2], Panic! at the Disco, Ariana Grande [3], Lil Nas X, a lot of Lizzo [4], and even a little Lady Gaga [5] by way of "Shallow" (A Star Is Born technically came out in 2018, but we'll allow it). Give it a listen above, and then check out the DJ's extremely nostalgic mashup of the decade's best pop songs [6].
