I am known for mainly covering rock music but when a group like Pentatonix comes out with something new, you know you are in for a treat. Pentatonix has just come out with their rendition of one of the most powerful songs ever written, Hallelujah. With the Holiday Season coming up this is a perfect song to get you ready for it. A beautiful song by one of the most powerful groups on this planet. If you never heard of them before, you will remember their name after hearing this.
