Pentatonix marks major milestone with a cappella Justin Timberlake cover

(CBS News) To celebrate an online musical milestone of hitting 1 million YouTube subscribers, Pentatonix has released an a cappella cover of a certain singer/actor/celebrity/icon well-known for bringing "sexy back." (I still contest I came in at least a close second.) Watch them perform "Pusher Love Girl" employing their amazing vocal medium in the music video above.

The completely live rendition of Justin Timberlake's hit song (with no auto-tune or overdubbing done) just reinforces why they've hit this milestone and continue to be total "a cappella rockstars." Congratulations to Pentatonix on hitting over 1 million subscribers, and a big triple-rainbow salute of musical excellence goes out to them for this latest from all of us here at The Feed!
