Basically, Dre is trying to get into film scoring. A lot of his tracks lately have reflected that. If this track didn't have rappers on it, you could play this in the background of a movie and it would fit.
Listen to "Live By The Gun" on Tony Yayo's album, "Get You Some", "Legend of the Fall Offs" on Busta Rhymes album, "Gunz Come Out" on 50 Cent's album.. shit even "The Setup" on Obie Trice's album to get an idea of the direction he's going in.
