Billboard caught up with Scott Hoying of a capella phenomenon Pentatonix to discuss the group's powerful cover of "Hallelujah," which appears on their 2016 album A Pentatonix Christmas -- and is currently climbing the Holiday 100.

Why do you think this particular Leonard Cohen cover from 2016 still resonates?

Scott Hoying: “Hallelujah” is one of the most iconic songs ever written. We made it really dramatic and emotional, and when people hear it, they feel something. We were originally going to put Christmas lyrics in it, but we wanted to honor the poetic original. It’s inclusive -- people who don’t celebrate Christmas can enjoy it.
