What do you get when the hottest club thumpin', fist pumpin' tunes of the year are mashed up into a single track? DJ Earworm has your answer in the latest edition of his annual mix, entitled, "United State of Pop 2011 (World Go Boom)" which features hit songs from artists you may or may not have heard of: Adele, Katy Perry, Lady Gaga, LMFAO, Rihanna — you get the idea. And if this track somehow doesn't satisfy your mainstream-listening needs, DJ Earworm's got mashups from previous years (2008-2010) on his YouTube channel as well. That said, go ahead and press play on the embed below, or feel free to download the song from DJ Earworm's site, for free.
