Taylor Swift Sings Eminem [VIDEO]

If you've ever been to a live show, you know that some bands and artists will give a musical 'shout out' by singing a cover of their favorite artists live in concert. Just a little something extra for the fans who are in that audience. Recently Taylor Swift was in Grand Rapids, Michigan and decided to sing Lose Yourself from Eminem, perhaps because Eminem is from Detroit. What do you think of this cover?
