I guess the good examples where music could be an important driver to the movies popularity (or revival of popularity) might be: "Requiem for a dream" and "Das Boot". Also for me personally - "The Mission" as incredible score by Ennio Morricone has brought me tia film I'd rather ignore. Other (also personal) example is " The Spawn" with it's mind-blowing OST.
