Foxes' cover of "Don't Stop Me Now" is fantastic, and hopefully you can enjoy it even if you don't watch Doctor Who (which the cover was sung for.)
I'm in choir, so I really enjoy Pentatonix's a cappella covers.
I have been watching Pentatonix clapping tutorial. Now I need 5 people to practice with. Hubski?
Pentatonix are awesome! Also Fleet Foxes are Awesomee!!! So I pretty much died when I first heard this piece. The first bit of Christmas music I've actually enjoyed in a while. (Band and choir have made almost every normal carol or hymn unimaginably dull for me.)
Pentatonix is a marvelously refreshing group, I'm so glad that I know about them. And I completely know what you mean about the hymns and carols! (My choir is currently learning a 3rd version of Gloria...)
