Reality Rocks (New)

Pentatonix have really outdone themselves this time. The winners of NBC's recently renewed a cappella talent show "The Sing-Off" are already pitch-perfect YouTube sensations thanks to their many creative cover-song videos, but their latest megaclip, which has received more than 1.4 million views in just two days, truly is a sing-off of epic proportions.

Working their vocal cords to the max on everything from "Symphony No. 5" to "Bohemian Rhapsody," "Danny Boy" to "Boogie Woogie Bugle Boy," "Old Man River" to Bieber's "Baby," "Salve Regina" to Rihanna, PTX's five incredible singers deliver a crash-course sonic history lesson titled "Evolution of Music" that's as enjoyable as it is educational. Check out the video, along with a cheat-sheet of all the song titles, below--and get schooled, "Sing-Off"-style.
