Pharrell's song "Happy" from the Despicable Me 2 soundtrack is one of those songs that you hear and it immediately puts you in a good mood. I've loved the song since the first time I heard it, and I'm always excited when I see a YouTube video pop up of someone covering it.

I think I've discovered a video of the best "Happy" cover of all time, though. Thirty-ish students from the Detroit Academy of Arts and Sciences took on the song, and the result is pretty amazing.

The video of the kids' performance has gone viral on YouTube, and the school's CEO hopes that its popularity will help raise funds for a trip to Disney for the kids so that they can perform there.
