We all know Pentatonix has a way with cover songs - and their latest performance is no different!

With Christmas just three months away, the quintet have belted out a powerful cover of 'Joy to the World,' which features on their new holiday album Holidays Around The World.

Putting their signature spin on the iconic Chrismas song, the five singers - Scott Hoying, Mitch Grassi, Kirstin Maldonado, Kevin Olusola and Matt Sallee - allowed their flawless harmonies to shine.
