Look out, New York City. The New Directions are bringing an original song to Nationals.

On the May 24 season finale of Glee, Rachel, Mercedes and company will take on the best choirs in the nation. And they'll do so armed with "Light Up My World," the latest single penned especially for this Fox hit.

Ryan Seacrest debuted the track on his radio show today and we hear shades of "Loser Like Me" in it. Give it a listen now and chime in: think it will carry William McKinley to the Nationals title?
