From 'Little Green Bag' to '100 Black Coffins'
John Legend, "Who Did That To You" ("Django Unchained")
Tarantino's latest film includes a quartet of original songs in addition to source music used here and there, and perhaps most electrifying is John Legend's "Who Did That To You." With its Paul Epworth-produced grit and swagger, the song gives vengeful, righteous voice to the titular hero. - Kristopher Tapley
