The Rihanna promotional train is now moving at full speed.

After releasing the singles "FourFiveSeconds,"Higher" and "Dancing in the Dark," the Bajan beauty drops another new track, "American Oxygen." The song previewed during an NCAA March Madness commercial that will air for the rest of this month.

The clip is only 30 seconds long, so you only get to hear a snippet of the cut, but it's enough to give you an idea of what it sounds like. "Breathe out, breathe in, American oxygen / Young boy listening, trying to get the wheels in motion ... Breathe in this spirit, American oxygen ... This is the new America," she sings.

RiRi also appears in the commercial and looks stunning. Dressed in jeans, a t-shirt and a black leather jacket, the 27-year-old singer looks edgy but beautiful, as the simplicity of her outfit works tremendously.

As far as Rihanna's new album R8, there's still no word on when it'll be released. It's likely she'll pull a Beyonce and drop the whole thing without warning. It's been three years since the Roc Nation artist released her last album, Unapologetic.

In a recent interview with Official Charts, Ne-Yo, who worked on the album, said the fans are really going to love it, although, he's not sure if the songs that he wrote will make the cut. "I don't know what's going to be kept and I don't know what's going to happen with it," he said. "I personally feel like when it comes out, people will forget about how long the wait was. It'll definitely be worth the wait. What I've heard so far sounds unlike anything else."
