Do you remember which popular songs you played over and over again this past year? Do you have no time to listen to all of those songs? Don't worry, because DJ Earworm has returned with the latest edition of his annual "United States of Pop" mash-up.

Debuted on Thursday, December 2, the new mash-up titled "50 Shades of Pop" is made up of 50 fan-favorite hits, double the amount of songs the DJ included in the previous installments. Dominating the megamix are chart-toppers like Justin Bieber's "Where Are U Now", "What Do You Mean?" and "Sorry" as well as Taylor Swift's "Blank Space", "Style", "Bad Blood" and "Wildest Dreams".

Also featured in the mash-up are hitmakers like The Weeknd ("Earned It", "The Hills" and "Can't Feel My Face"), Adele ("Hello"), Mark Ronson ("Uptown Funk" with Bruno Mars), Drake ("Hotline Bling"), Maroon 5 ("Sugar"), Ed Sheeran ("Photograph" and "Thinking Out Loud") Ellie Goulding ("Love Me Like You Do") and One Direction ("Drag Me Down").

"It's a more eclectic mix than it was five years ago. I try to get a feel of what is in the zeitgeist," DJ Earworm told Billboard of the diverse mix. "Music has been going through a softer phase than it was a few years ago so there's that return of adult contemporary. That's maybe represented by the Ellie Goulding track, it's very lush and soft. And then there's sort of retro, uptempo dance stuff, and that's represented by The Weeknd track."
