Pentatonix — one of the most awesome a cappella groups out there — put together a special medley of Beyoncé's biggest hits and it's amazing.
The group, whom you might recognize as the winners of the third season of The Sing Off, put the medley together in honor of reaching a half-million Facebook likes on their official page, and to honor the general fabulousness of Bey.
We think B would approve.
Pentatonix's second album, PTX Vol. 2, comes out Nov. 5.
