There are some amazing covers of songs done by a homeless man nicknamed "mustard" on the Opie and Anthony show. He is most famous for his cover of Radiohead's creep. Where you come in is by helping me identify the last song on the list on this website: http://opieandanthony.tumblr.com/post/286862717/mustard-audio. And so this thread isn't a complete waste, what are some of you favorite covers of songs or covers that you think surpass their original artist's interpretation?
