B.o.B teams up with rock band O.A.R. to record a new song in an effort to help motivate Team U.S.A. in upcoming Olympic Games. Inspired by the rigorous training and determination of the athletes, the track titled "Champions" is released as a free download.

"I think the song is very synonymous with challenges that many people face in life even beyond the field, beyond the court and beyond the sports," B.o.B told Yahoo! Music Canada. "It's the same place you have to dig from and challenge from when you're an athlete or at an Olympian level. This is the best the world has to offer."

O.A.R. had been working on the song for a year when they were contacted to craft an anthem for the Games. They thought the unfinished song was a perfect fit, so they immediately revisited it and then asked B.o.B to be on it. "This is an artist that is not just a rapper, not just a musician, not just a singer or songwriter, he's done it all," gushed singer Marc Roberge.

"This record, sonically, was intended to sound regal, like something that kinda encompasses the Olympics," he continued. "When you look out along the field, you imagine trumpeters and drums pounding like the opening of the Olympics and that's what we went for."

The song was recorded as part of Duracell's "Rely on Copper to Go for the Gold" program that supports the 2012 Olympic Games in London. Those who download the song are encouraged to be part of the campaign by sending messages of encouragement via videos, pictures and texts.

The anthem will be showcased on national television for the very first time on "The Tonight Show with Jay Leno".
