"Don't worry, be happy" would be the feeling today after Nota, a Puerto Rican a cappella group, won NBC's Sing Off competition.
It was announced last night that the six man vocalists had won the $100,000 cash prize and Sony recording contract.
The winners beat out a college group, the Beelzebubs, based out of Tufts University, Massachusetts.
The finale showcased the show's finalists and several featured acts such as a Boyz II Men who put together a medley of classic hits such as End of the road. Nicole Scherzinger of the Pussycat Dolls, who was a judge on the show, teamed up with the Beelzebubs, singing 1964 hit You don't own me.
The night also featured song and orchestration by judge and ten-time Grammy award winner Bobby McFerrin. He put on an impressive polyphonic performance that included song improvisation with finalists Nota, Beelzebubs and Voices of Lee.
