I'm not sure what there's more of on the internet right now, covers of Disney's Frozen, True Detective spoofs or parodies of that First Kiss video. 

Rather than subjecting you to another video of a 16-year-old giving it their best go at the song on (insert reality TV talent show name here) Brian Hull nails the song as Scar from The Lion King. In addition to the 20 other Disney and Pixar impressions he does. 

It's without a doubt the best cover of "Let It Go" you see for at least the next 12 hours, until somebody uploads cover done by a choir of kittens or something.
