Rihanna has been very secretive about her new album R8, with our only clues being the snippets she posted on social media. Tonight, she revealed a new song titled "American Oxygen" that will serve as the theme song for this year's March Madness coverage. The short clip is a very good preview of the triumphant and catchy song, which will fit the competitive nature of the upcoming NCAA tournament. Watch the commercial above, and listen to another song she previewed on her Instagram earlier today.
