Imagine putting together such big names in 2011 pop music like Bruno Mars, Britney Spears, Maroon 5, Adele and more in one hot video? This is what DJ Earworm was able to do by creating a mashup video of all the most popular songs of this year: "United State of Pop 2011 (World Go Boom)."

DJ Earworm (real name: Jordan Roseman) says on his site that the mashup got its inspiration from various emotions of anger, pride, perseverance, fire and regret. He based it on the weekly charts of the year 2011 and made sure that he included the latest hits of the year like "We Found Love" by Rihanna and also "Sexy and I Know It" by LMFAO.

Other artists featured include Lady Gaga, Katy Perry, Nicki Minaj, Pitbull, Foster the People and a lot more.

Check out the great mashup below:
