This music comes from the closing credits of Stranger Things season 5, the final chapter of Netflix's long-running supernatural series about Hawkins, Indiana and the Upside Down. The show's synth-led sound has been part of its identity since it began, so its closing themes are instantly recognisable to fans even in short clips. As season 5 arrived, viewers began sharing its end credits audio for recaps, reactions and tributes, using the short excerpt to signal that an episode or a storyline had reached its end. It remains popular because it works as shorthand for the series itself.
