2019 was one of the most thrilling years in music, a year dominated by new talent and driven by listeners and consumers, whether by organized fandom or by TikTok trends. It was the year we saw Lil Nas X, Billie Eilish, and Lizzo thrive by defying labels. It was the year Latin trap continued to find mainstream success. It was the year that gave us an unprecedented amount of women rappers on the charts. And of course it was the glorious year that finally put Mariah Carey’s “All I Want For Christmas Is You” where it belongs: number 1.
