Okay, so they're not really played at once. But this mashup of Katy Perry, LMFAO, Rihanna, One Direction, Carly Rae Jepsen, and more will make you question whether we aren't just listening to the same song on repeat whenever we turn on the radio.
We know, we know. You've heard both of these songs a million times before, and not even an adorable mashup of the two by Pomplamoose might keep you from rolling your eyes and saying "UGH, not AGAIN" (did you do that? Be honest!) But this arrangement is executed well enough to be worth your time, and the music video defies the obvious visuals by paying homage to the 2009 thriller "The Box" (or possibly "Button Button" by Richard Matheson, the short story on which the movie was based).
