After Green Day's Billie Joe Armstrong created something of a commotion by walking off the stage Friday night in a profane laced tirade, things got back to business Saturday.  Taylor Swift, Linkin Park, Pink, Enrique Inglesias, Brad Paisley and Mary J. Blige sang some of their latest hits to a packed Las Vegas audience.  One highlight was Ne-Yo and Calvin Harris performing together.
