Electro house musician Daniel Kim has created a mashup video of 50 of the best(?) pop songs 2012 had to offer. Carly Rae Jepsen. Gotye. LMFAO. Ke$ha. The Biebz. Fun. Maroon 5. Katy Perry. Ugh, Chris Brown. Nicki Minaj. More Fun. The video is eight minutes long and definitely greater than the sum of its parts, if only for the way Kim integrates the songs. Definitely worth a few minutes of your time, but, be careful, your head is sure to explode if you watch it more than once.
