'Somebody That I Used to Know'/'Call Me Maybe' Mash-up: Pomplamoose Cover Combines Two Catchiest Songs EVER

Just when you thought you had successfully cleared both Gotye's infectious "Somebody That I Used to Know" and Carly Rae Jepsen's "Call Me Maybe" from your head, Pomplamoose is here to set you back to square one. The indie duo just dropped a mash-up to end all mash-ups -- the mash-up apocalypse, if you will -- of the two catchiest songs of the year!

Multi-instrumentalists Jack Conte and Nataly Dawn are the evil geniuses plotting to take over our our ears, and the Internet, with the new viral video. And when Pomplamoose named the track "Do Not Push," they meant it. As soon as you press "play," brace yourselves! You've been forewarned ... listen to the Gotye/Carly Rae Jepsen mash-up, below.
