People who aren't aware of Canadian pop music or the listening habits of Selena Gomez might not know the original version, but I think everyone can agree that this cowbell remix succeeds in perfecting the unperfectable.
With all the Call Me Maybe parodies and covers infesting the internet, it's about time the singer herself appeared in one of them. This percussion-themed cover with Jimmy Fallon and the Roots is a nice change of pace from the string samples in the original song, too.
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.
