The simple song is currently the most popular track available for download on iTunes off the movie’s soundtrack. It even managed to climb Billboard’s Hot 100 list. The song is so hot that an extended, more produced version of the track has been made and soon it will find its way to radio stations this month.

The radio version is called “When I’m Gone” and you can preview it in its entirety in the box embedded above. And if you still haven’t seen Pitch Perfect, what are you waiting for?!
