Ready Player One is full of 1980s nostalgia, and the film's soundtrack plays a significant role in this. The 2018 Steven Spielberg movie is set in a futuristic time when humanity prefers a virtual world to a real one. It focuses on the media of the past, from movies, TV shows, video games, and, of course, music. Therefore, as Wade Watts, AKA Parzival, searches the OASIS for Halliday's Easter egg, he is accompanied by an excellent soundtrack featuring some of the biggest hits of the late 20th century.
