That's your New Year's Eve countdown song sorted anyway.

Every year, DJ Earworm brings the world his pop mashup of the year, and while the last few year's efforts have been pretty meh in comparison to his 2009 mix, 2014's mashup 'Do What You Wanna Do' is genuinely brilliant.

Made up of the top 25 biggest U.S. songs of the year, 'United States of Pop 2014' features everyone from Taylor Swift, Katy Perry and Iggy Azalea to our very own Hozier and a sneaky bit of Frozen's 'Let It Go'.

Who thought Take Me To Church and Dark Horse/Black Widow/Pompeii would mix so well?
