Let's be real: songs in a movie can really make or break a scene because they set the tone for what viewers can expect. Once Upon a Time in Hollywood [1] lives up to the nostalgia in the subtext of its name, not just in plot but in the music. Directed by Quentin Tarantino [2], the movie — which stars some of the biggest names in Hollywood, including Brad Pitt [3], Leonardo DiCaprio [4], and Margot Robbie — is an ode to 1960s Los Angeles with all its highs and lows [5]. The movie musically dovetails with retro classics from the 1960s that transport viewers to an older time. Tunes from Los Bravos, Simon & Garfunkel, Neil Diamond, Deep Purple, and so many more make appearances [6] with a smattering of "era-specific" radio commercials that are also included on the soundtrack. Check out the official soundtrack to the movie that Tarantino himself curated — these songs just may entice you to throw a '60s-themed party!
