Kate Bush's 1985 ballad "Running Up That Hill" has made the charts once again thanks to its use in the Netflix series Stranger Things. In season 4, episode 4 of the series — titled "Dear Billy" — the song saves Sadie Sink's character Max in a face-off with the show's previously unseen antagonist Vecna. It also serves a dual purpose of reflecting Max's state of mind having lost her brother, Billy (Dacre Montgomery), in the season prior, as the lyrics go: "And if I only could, I'd make a deal with God, and I'd get him to swap our places."

Music is an integral part of many TV shows, but especially Stranger Things which relies on it to fully plunge viewers into the 80s. The viral scene from above is just one example of the show using music effectively, and with too many examples to list, this article selects the best musical moment from each season so far.

Season 1: "Should I Stay Or Should I Go"

It's a classic scene in many movies and TV shows: the older sibling lets the younger sibling in and teaches them how to be "cool" — or in this case, how to embrace nonconformity. Jonathan (Charlie Heaton), the older brother, first hears The Clash's "Should I Stay Or Should I Go" on his car radio. In a flashback, viewers then see him share the song with his younger brother, Will (Noah Schnapp), who immediately takes a liking to it. "You can keep the mix if you want," Jonathan tells him; "All the best stuff's on there, Joy Division, Bowie, Television, The Smiths, it'll totally change your life."

What's even more heartwarming — or heartbreaking — about this interaction is that it takes place whilst their parents are arguing (pretty loudly) on the phone about Will's dad not showing up. To the question, "Should I Stay Or Should I Go," Lonnie (Ross Partridge) chose the latter, but what does that matter when you've got a cool older brother with good music taste and sound words of advice like "You shouldn't like things because people tell you you're supposed to."

Season 2: "Time After Time"

There's a lot of saving and being saved that happens in Stranger Things season 2, but this musical moment isn't one of those life-or-death situations. Rather, Nancy (Natalia Dyer) saves Dustin (Gaten Matarazzo) from public humiliation here to the tune of Cyndi Lauper's "Time After Time." At the Hawkins Middle School Snow Ball dance, Lucas (Caleb McLaughlin) expresses his feelings for Max, Mike (Finn Wolfhard) and Eleven (Millie Bobby Brown) share a moment, and even "Zombie Boy" (Will) gets asked to dance, whilst Dustin — with his ridiculous hairdo — is continuously rejected by the ladies.

Silently sobbing on the bleachers, he is spotted by Nancy who, feeling sorry for him, leads him to the floor. Nancy might not have been his first choice (Dustin makes it very clear he's into Max), but she is up there, and the two have a great time slow dancing and annoying his bullies in the process.

Season 3: "The NeverEnding Story"

Gabriella Pizzolo makes her first appearance as Suzie in the season 3 finale, and boy is it one to remember. Throughout the season there is a running gag that Dustin's summer camp girlfriend, Suzie, is imaginary; however, whilst Dustin's description of her as "think Phoebe Cates only hotter" isn't quite true, it turns out he wasn't lying about everything. Suzie does exist, and viewers are grateful for it.

In this episode, the gang are after a vault code that will save the world when they require Suzie's assistance. Dustin is able to get through to Suzie via walkie-talkie, but because he hasn't contacted her in a week, she is unwilling to hand over the code so easily. Instead, she wants something in return: a duet. Cue Dustin and Suzie singing their hearts out to The NeverEnding Story theme tune, and the gang, amazed, listening from their walkie-talkies.

Season 4: "Running Up That Hill"

There are some great song choices in season 4 of Stranger Things, but no musical moment tops Max facing off with Vecna and being saved by Kate Bush — there's a reason why this scene (and song) went viral. "Running Up That Hill" makes several appearances in this season as Max's favorite song, but has its moment to shine after Nancy and Robin (Maya Hawke) discover music is Vecna's weakness.

When Max is possessed by Vecna and taken to the Upside Down, Dustin, Lucas, and Steve (Joe Keery) use the girls' advice to bring her back. Putting headphones on Max, they blast her favorite song — and it works. In the Upside Down, Max hears the music, and happy memories, including shopping with Eleven and trick or treating with the boys, flash before her eyes. Suddenly she has the strength to fight off Vecna and join her friends in the real world. And that's on the power of music.

Stranger Things is available to stream on Netflix.
