Apparently there is this show called the Sing-Off on NBC that is hosted by Nick Lachey which I am just hearing about. I was clearly late to the game on this one but now that I know let me tell you about it. The Sing-Off is a singing competition where the groups sing a cappella and last week was hip hop week so all the groups did covers of popular hip hop songs. My favorite performance was of Kanye West's Love Lockdown covered by Pentatonix. It was amazing! If they don't win the competition they definitely can have a Youtube career covering hip hop songs. Check out their performance below.
