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.
