American mash-up artist DJ Earworm has released his 2015 United States of Pop mega-mash of the year's biggest hits.
Earworm, real name Jordan Roseman, is widely known for his annual mash-ups which bring together music website Billboard's top songs of the year and mixes them into one extended track.
His 2015 effort, titled 50 Shades of Pop, features vocals and beats from 50 hits from the likes of Adele, Taylor Swift, Justin Bieber, The Weeknd and Maroon 5.
Earworm said the mash-up reflects the evolution of music throughout the year.
"I try to get a feel of what is in the zeitgeist," he told Billboard.
