THE WEEK Dec 28: Viral songs of 2012

Carly Rae Jepsen - Call Me Maybe

Canadian sensation Carly Rae Jepsen's "Call Me Maybe" exploded this year, and if you say you have never screamed this song at the top of your lungs, you're lying. The song was so popular it sparked people - from professional cheerleaders to soldiers - to create music videos of their own.

Psy - Gangnam Style

If this song didn't have you tripping over your feet trying to do some crazy leg moves and swinging your arm around your head, then you are the Scrooge of pop music. This song has broken nearly every record for Internet videos. It's nearing 1 billion views on Psy's official Youtube page. It's success is so mind-blowing, some of America's biggest news anchors tried to figure out what made it so famous.

Gotye - Somebody That I Used To Know

Belgian-Australian musician Gotye captivated mass audiences this year with his heart-wrenching melodies and tear-jerking harmonies. Though the song was originally released in 2011, it didn't gain its incredible fame until 2012. Now, "Somebody That I Used To Know" has been included on nearly every list of the year's biggest songs. It's been covered on multiple TV singing competitions.

Walk off the Earth

I got into the Canadian group Walk off the Earth when they covered Gotye's "Somebody That I Used To Know". The video was famous because the group of five musicians performed the song while all using the same single guitar. If you haven't heard or seen this group, check them out right now. This band of creative musical minds will treat you to hilarious, sad and awesome tunes that are made even more awesome by their uniquely constructed music videos.
