@inthehands I'll add that Tori's cover of Eminem's "'97 Bonnie & Clyde" is one of the most terrifying and stunning covers I've ever heard. It's hair-raising when you listen to that and realize she's re-done the song *from the perspective of the murdered woman*. I think the cover version is so amazing that she effectively wrests ownership of the song from Eminem.
(A similar wresting of ownership: Johnny Cash's cover of the Nine Inch Nails "Hurt".)
