Bless DJ Earworm, the producer whose real name is Jordan Roseman, for continuing his yearly ‘United State of Pop’ mash-up extravaganza. Earworm splices together dozens of the year’s biggest hits into one track, and his 2015 opus has arrived.

There are a lot of moving parts here (as always), but the Weeknd seems to be a recurring theme, as does that inescapable synth riff from Omarion’s “Post To Be” and that “Yes pleeeease!” from Maroon 5’s “Sugar.” There’s one movement that’s completely “Hotline Bling” and “Love Me Harder” that may be the best section of all.

"It's a more eclectic mix than it was five years ago," Roseman, who’s been unleashing United State of Pop mash-ups since 2007, tells Billboard. Kudos to the man for squeezing in Adele’s “Hello,” after dropping so late in the year. “It wouldn't be a year in summary without her,” he explains.
