Everything Is Awesome - The Lego Movie.

The Lego Movie - Everything Is Awesome.

This plays the same looped song for 10 hours.  There's also a different version around as well.  Anyway this is a 10 hour youtube video.

Adding it cause it's awesome and the first time I heard it was when I saw the movie.  Apparently there's going to be 3 more Lego movies.  Yay
