Ah, 2009 is done. Finally. This year, the pop charts were dominated by electro synthesized beats (hello 1980's), thanks to the likes of Lady Gaga, the Black Eyed Peas, Pitbull, and the rest of the band of misfits that rule the airways.
But just in case you found yourself in a sensory depravation unit the entire year, DJ Earworm, a mashup genius, put together all this year's hits into one slick video.
The overall mashup has the "I gotta feeling" backbeat pumping up the chopped up choruses of Billboards Top 25 songs of 2009. Enjoy.
