Pharrell's upbeat tune 'Happy' is everywhere -- it's on a constant loop on the radio, in the film 'Despicable Me 2' and was even nominated for an Academy Award. But you've never heard the song like this before!

The kids in the choir at the Detroit Academy of Arts and Sciences covered the hit song in a flawless performance that showcased the their killer harmonies. The students are adorable -- but beyond that, they are genuinely talented, harmonizing in a way that breathes new life into the song and gives it a fresh twist. Each of the soloists -- including a charismatic little boy and a young girl with a voice that is mature beyond her young years -- rock their parts perfectly as everyone claps along and belts out the tune with smiles on their faces.

We love it!
