vinyl, and cassette. In addition to Dixon and Stein's original soundtrack, the season features several songs selected from the 1980s and earlier eras. Legacy Recordings released a 16-track compilation of these songs on July 5, 2019. The finale of the episode "E Pluribus Unum", particularly the scenes involving Eleven's telepathic encounter with the Mind Flayer-possessed Billy, contains excerpts of "Confrontation and Rescue" from the second act of Satyagraha by Philip Glass. Of note was the use of "The NeverEnding Story", the theme to the 1984 film of the same name, which is used in the final episode when Suzie refuses to provide the critical code until Dustin sings it to her. The Duffers had wanted to introduce Suzie into the show's narrative in some dramatic fashion while giving Matarazzo, who has sung on Broadway before, a chance to show off his own vocals. Initially, they were planning to use "The Ent and the Entwife" song from The Lord of the Rings, but aware that Amazon Studios were developing its own Lord of the Rings series, decided to change direction. The Duffers credit writer Curtis Gwinn for using "The NeverEnding Story" as the replacement. Matarazzo and Gabriella Pizzolo, the actress playing Suzie and also a seasoned singer on Broadway, were on sets near each other when they sang the song together and were able to harmonize the song as well without the backing music. As their characters were not meant to be in that much synchronization due to being in two different places, the song's backing track and some autotuning were used to blend their singing to their respective settings and the tone of the soundtrack. According to the cast and to composers Kyle Dixon and Michael Stein, the song became an earworm for many of the cast on the day that scene was filmed. Later in the episode, Lucas and Max, played by Caleb McLaughlin and Sadie Sink, sing the song in duet back to Dustin to mock him; both McLaughlin and Sink also have had experience in Broadway musicals. As a result of its appearance in the series, "The NeverEnding Story" drew an 800% increase in viewership and streaming requests on YouTube and Spotify over the days after initial broadcast, putting Limahl, the song's artist, briefly back in the spotlight.
