As for how well this 3 minute feature was executed, well it's not quite as informative as the other two behind the scenes features—if this weren't a strict music video I would have loved to have gotten an idea of who many takes this recording session took—but in exchange you get to watch Tay Diggs have fun singing for the duration of the song in the recording booth. Interspersing live action footage with finished animation is a common enough bonus feature in animated movies releases, and this one does it competently.
Be sure to take a look when you get your hands on it.
