The iHeartRadio Music Festival this year has featured some of the biggest names in music with a show that seems larger than ever.  It was big and it was loud, and at times the crowd seemed a little quiet for whatever reason, though it never lasted long.  Great sets by all with some big songs gives iHeartRadio a successful fourth year at the MGM Grand in Las Vegas.
