Pardon me if someone already mentioned this but I came across this last night. She has 1.6 million views and has already got IGN's attention who made a video using her cover of the song. A few other gaming blogs are running stories about it. Someone has even made a mod to put it in the game. It's her cover of "The Dragonborn comes"
