Burlington Ontario YouTube sensations Walk off the Earth (that group that only use one guitar for all of them to play at once, you know them!) have another internet hit on their hands, this time tackling Taylor Swift’s massive tune ‘I knew you were trouble’.  The group’s acapella take on the song strips the original of its sunshiney guitars and takes it in a slightly darker direction, seemingly giving it a remix that you would expect from the likes of Skrillex.  Take a listen to it below, and also check out the original while your at it as Taylor Swift turns in a decent bit of acting in the clip:
