"Everything is Awesome!!!" by Tegan and Sara, featuring the Lonely Island (Natives).

[The Lego Movie hit me hard (in the best way). It had all the humanity of your feel-good fiction, insanely clever, with a stunning insight to creativity. I enjoyed it immensely, and highly recommend it. Also, the Berkeley Boys are on the track, which is a good excuse to gush over my favorite family film since Wreck-it-Ralph and Paranorman.]
