Mr. Guetta specializes in dancefloor killers, and you know he saved something special for Rihanna. The song is all about the here and now. "Tomorrow's way too far away/We can't get back yesterday..." When all you've got is right now, you might as well dance like your life depends on it. And this song would be a fitting soundtrack. "Something you wanted to do all your life/There's no more waiting tonight is the night."
