It was only a matter of time before Ryan Gosling and Emma Stone turned their continuous onscreen romance into a full-blown musical. At last, the moment has arrived with La La Land. You’ve seen the trailers, swooned until it hurt, and heard a snippet of Gosling crooning his way into Stone’s heart. Well, brace yourselves, because the film’s standout duet “City of Stars” has arrived in full to put a tear and, er, a twinkle in your eye. Get swept up in their big-city dreams, giggle when Emma giggles, and remember that as your heart swells with every note, it’ll likely explode by the time these two inevitably perform it at the Oscars. Ahhh, young love. The film’s soundtrack, featuring even more of Emma and Ryan’s musical meet-cutes, drops December 9.
