Walk Off The Earth's "I Knew You Were Trouble" Cover Goes Viral

Canadian indie band Walk Off The Earth is well known for their covers of some of pop's biggest songs. From "Someone Like You" to "Somebody That I Used To Know", the talented group uses all kinds of instruments — even their voices — to create these extremely likeable covers. On January 1st, WOTE uploaded their Taylor Swift "I Knew You Were Trouble" cover using only vocals to YouTube, and now only two days later, the clip has over a million hits! Can you believe that they made those computerized sounds with only their pipes? Neither can we!
