A lot of people have taken a crack at the beautiful song, "Let It Go" from the movie Frozen, but this may be one of the better versions I've heard.  Watch as Cassadee Pope sings to patients at Vanderbilt Children's Hospital.As a dad of two small kids, I hear this Oscar winner every single day, but somehow, Cassadee's acoustic take on it breathes new life into an already awesome song that was getting old for me.
