Mashup master DJ/producer DJ Earworm's annual “United State of Pop” mashup mixes of the year's 25 biggest Billboard Hot 100 pop hits have become an anticipated event at the end of each year since the San Francisco based DJ began doing them five years ago. Earworm's brand new United States of Pop 2012 (Shine Brighter) mix, which was premiered last Saturday night at 11:30pm atBootie SF at their weekly party at the DNA Lounge in San Francsico (tonight's thier Post Apocalypse Bootie party), finally got uploaded for fans to hear on Tuesday (Dec 18th) on both SoundCloud and on YouTube. DJ Earworm, born Jordan Roseman, does the great video mixes too, and in the four days since he posted the new mix has gotten close to million and a half YouTube views. Subtitled Shine Brighter the United States of Pop 2012 is an exercise in how to seamlessly inter-weave all of these disparate 25 tracks and make them sound like one perfectly cohesive track. Peep the video above and see how of the songs/artists you can name. Below is a complete list of them all and yes it includes "Gangnam Style."
