DJ Earworm Mashup 'United State of Pop 2014' Will Ring in Your Head for Sure

An internet tradition since 2007, DJ Earworm has been releasing his annual end-of-the-year mashup of the year's top pop songs online. This year's mix was released on Wednesday and entitled "United State of Pop 2014 (Do What You Wanna Do)."

DJ Earworm, who is Jordan Roseman in real life, compiled tracks from 2014's most popular songs from artists like Katy Perry, John Legend, Taylor Swift, Idina Menzel, and others.

The tempo of his seventh year-end mashup is much slower than previous installments. DJ Earworm blames it on the lack of upbeat, danceable hits.
