Quentin Tarantino’s new film, Django Unchained, will be hitting theaters on December 25. Before the release, fans will be getting a taste of it through a soundtrack that features a new solo Rick Ross song, as well as this impressive mash-up.

Rolling Stone premieres “Unchained (The Payback/Untouchable”) that showcases ‘Pac’s engineer Claudio Cueni’s mixing abilities. He brings the funk of Brown’s “The Payback” with the infectious hook from “Untouchable” for a slick offering. Listen to it below.
