Must Watch: DJ Earworm's Usher/Justin Bieber/Ke$ha Summer Song Mashup

Last year, DJ Earworm neatly summed up 2009 in just a few brief, blissful minutes, mashing up 12 months' worth of hits into just under five minutes. It was called "United State of Pop," and it was awesome.  The work incorporated songs from Black Eyed Peas, Kelly Clarkson, Taylor Swift, Jay Sean and many more.

Well, Earworm has done it again, and we didn't even have to wait 12 months. The talented, multimedia-masher is back with a video for the songs of the summer called "Like, OMG, Baby."

With a backbone of tracks such as Ke$ha's "TiK ToK," Usher's "OMG" and Justin Bieber's "Baby," Earworm throws everything at us: from Jason Derulo to Rihanna to JLS and everything in between.

It's a pretty ecstatic picture of pop right now. Check out the video below.
