We're thawing out the five most popular songs in the Billboard Hot 100 Pop Singles chart, for the week ending Dec. 23, 2017. It's a festive time of year for many of us, so here's something to celebrate: a new number one single! Number 5: Imagine Dragons "Thunder" Imagine Dragons remains your fifth-place act with "Thunder." We're only about six weeks away from the Super Bowl … and this band will take part in the festivities. On Feb. 1, 2018, Imagine Dragons will give a headlining performance in Minneapolis, Minnesota — site of Super Bowl LII on February 4. Machine Gun Kelly and Mura Masa will be the opening acts. Number 4: Lil Pump "Gucci Gang" Lil Pump spends another week in fourth place with "Gucci Gang." Why did he throw a microphone at a fan? Earlier in December, the 17-year-old rapper prematurely ended a show in Wallingford, Connecticut, after a spectator threw a water bottle at him. Pump chucked his microphone into the crowd and left the stage. He later went on Twitter to apologize … but not to the person who threw the water bottle. Number 3: Camila Cabello Featuring Young Thug "Havana" Camila Cabello and Young Thug step back a slot to third place with "Havana." Speaking with DJ Zane Lowe, Camila says her upcoming solo album will drop on January 12. She says the album reflects her desire to move on from a heartbreak, and the name change enabled her to take charge of the situation. The album originally bore the title "The Hurting, The Healing, The Loving." Number 2: Post Malone Featuring 21 Savage "Rockstar" After eight weeks at the top, Post Malone and 21 Savage lose the Hot 100 championship with "Rockstar." On December 15, Post dropped the Latin remix featuring Nicky Jam and Ozuna. You can hear it on our Twitter page, RayOnTheHits, and our Facebook page, VOA1TheHits. Number 1: Ed Sheeran Duet with Beyonce "Perfect" Remixes are all the rage right now … in fact, that's what we get at No. 1. Ed Sheeran scores his second career Hot 100 victory with the remix of "Perfect" featuring Beyonce. She's an old hand at topping the hit list: This is Beyonce's sixth solo title, along with four more with Destiny's Child. It's also her first championship since "Single Ladies" reigned for four weeks in December 2008. Can they last two weeks at the top? We'll find out in seven days!
