Just separate "Score" (which Django has elements of) and "Soundtrack" (which is what the thread is titled and which most if not all of the other westerns mentioned don't have) and call it a day.
Django's soundtrack, full of all kinds of music that fits together amazingly somehow, probably blows away all other western soundtracks.
