It's that time of year again -- DJ Earworm, the man best known for his annual mashing-up of the top 25 songs on Billboard's year-end Hot 100 chart, is back with "United State of Pop 2010."

As the chart reveals, dance-pop ruled in a big way this year, and that's also reflected in DJ Earworm's latest offering. "United State of Pop 2010" includes Lady Gaga's "Bad Romance," Taio Cruz's "Dynamite," Rihanna's "Rude Boy," Enrique Iglesias' "I LIke It," Katy Perry's "Teenage Dream and "California Gurls," Usher's "OMG" and, of course, the year's biggest Hot 100 hit -- Ke$ha's "TiK ToK."

Take a listen, and enjoy the year's most ubiquitous tunes one last time before ringing in 2011.
