This week was out with the old and in with the new, as stars and fans alike said goodbye to the 2010s by ringing in the new decade. 2019 came to a close with Mariah Carey continuing to celebrate the landmark success of "All I Want for Christmas Is You," which earned the Queen of Christmas her record 19th No. 1 Streets Talkin Hot 100 hit and led to another major chart moment for the icon as we turned the page to 2020.
BTS, Post Malone, Jonas Brothers and more may have celebrated the new year with Dick Clark's New Year's Rockin' Eve, but The Strokes, Dead & Company and others bid farewell to 2019 with their own shows from New York City to Los Angeles. And while Britney Spears and New Kids on the Block's Donnie Wahlberg were determined to start the new year off on the right foot with positive resolutions and generous surprises and Coachella dropped its 2020 lineup, Justin Bieber graced his Beliebers with the greatest gift of the year (so far) in the form of his much-anticipated new single, "Yummy," on Friday (Jan. 3).
Take a look at some of the best and brightest moments in music this week below.
