So I've got a thing for covers. Love 'em. Something about being like "Wait-- I know this song... don't I?" To me, the best covers stay true to what made the song great in the first place, but add in something new and unexpected from the the covering artist.
Buzzfeed just blew our minds with this amazing list of songs most people think are originals, but low and behold, they aren't. Torn by Natalie Imbruglia not original? Whaaaaaat? R-E-S-P-E-C-T not Aretha's song. The horror?
