YouTube still

You might just start your own praise circle while listening to "Hallelujah," a cover of Leonard Cohen's song that's expertly delivered by the fivesome known as Pentatonix.

[UPDATE Nov. 11: Pentatonix's chilling cover seems all the more relevant now that Cohen has died at age 82. Their tribute will help you remember one of Cohen's best-known songs.]

Arlington-rooted vocal group Pentatonix takes home first Grammy

Kirstin Maldonado, Scott Hoying, Mitch Grassi (who, all three, are from the Arlington area) with Avi Kaplan and Kevin "K.O." Olusola deliver "Hallelujah" with exquisite depth -- and with no instruments. (Pentatonix is an a cappella group.) "Hallelujah" is an early sign that, yes, Christmas is coming. Winter, too. With a song this breathtaking, we aren't even mad about it.

"Hallelujah" went on YouTube three days ago and had already seen nearly 7 million views at the time of this writing.

It'll give you goosebumps -- and not the scary kind. (It is that time of year, after all.)

Pentatonix's timing is perfect, of course, as it's currently fronting its third holiday album, A Pentatonix Christmas

Pentatonix / Us The Duo

The band has expertly used YouTube to promote its sweeping harmonies with online videos that are at times showy, others solemn. Nearly all feel sincere, though: The band is a group of buddies who won The Sing-Off in late 2011 and skyrocketed to success. Pentatonix's young, vocal army of followers are nuts for a cappella in world where being a Gleek is cool. The band's most popular video, a mash-up of Daft Punk's biggest hits,  garnered 212 million views. Pentatonix is truly an internet sensation.

Pentatonix has found success in Christmas records, specifically, and its holiday videos alone have netted more than 340 million views on YouTube, according to a statement from the band.

Pentatonix is currently on a U.S. tour that stops at the American Airlines Center in Dallas on Nov. 20.

If you enjoyed the video above, take another look at what Pentatonix can do: In 2013, the group took on Beyonce's best songs, starting way back in her Destiny's Child days. That takes guts:
