Original Song: Korean pop song-turned-Internet phenom "Gangnam Style," by Psy.
Cover Artist: A capella troupe Pentatonix (the guys behind this epic "We Are Young" cover)
How It's Different: The a capella rendition, of course, lacks the electronic pulse and synth stylings of the original song -- and also replaces Psy's crazy dance moves with some epic head-bobbing.
Why We Love It: When rendered by human voices alone, the thumping beat and fast-paced rap of the original song make for a surprisingly awesome -- and vocally impressive -- cover. Plus, the lead singer (or should we say rapper?) of Pentatonix can totally hold his own against Psy's rhymes.
Better than the Original? As much as we love the cover, Psy's legendary dance moves keep the original version in the #1 spot.
