The Duffer Brothers respond to the success of Kate Bush’s “Running Up That Hill” following its use in Stranger Things season 4. Bush originally released the song in 1985 as the opener to her album, Hounds of Love. Upon its original release, it gained notoriety both in the UK and U.S., as it reached #3 on the UK Singles Chart, and #30 on the Billboard Hot 100.,Now, decades later, “Running Up That Hill” is seeing a massive resurgence in 2022 after being featured in Stranger Things season 4. The Bush song helps prevent Max (Sadie Sink) from being killed by new villain Vecna and serves as the backing for the season’s climactic moment. Ever since the premiere of Stranger Things season 4 back in May, Spotify notes that streams for the song increased by 9,900 percent in the United States. “Running Up That Hill” also made it back onto the Billboard Hot 100 at number 8 on June 11.,Related: Stranger Things: Biggest Unanswered Questions & Mysteries After Season 4,In an interview with Collider, Matt and Ross Duffer discuss the newfound popularity of “Running Up That Hill.” Matt takes the lead in explaining their surprised reaction to the song’s success, revealing that either of them anticipated it becoming a huge thing. He says:,”Running Up That Hill” works so well in Stranger Things season 4 because of how it fits within certain themes. The song is about a man and a woman making a deal with God in order to switch places with each other, and therefore get a better understanding of one another. Max closes herself off in Stranger Things season 4, particularly from Lucas, and by playing this song, it shows that she is still yearning for connection with him. However, the thought of deliberately opening herself up to him is scary and difficult. Similar to Bush’s song, it would ultimately be a relief if someone such as Lucas could spend a day in Max’s shoes.,The subsequent success of “Running Up That Hill,” although not an intentional act by the Duffer Brothers, has brought attention not only to the song, but to Stranger Things season 4 as well. Several 80’s classics such as “Should I Stay or Should I Go” by The Clash, “Every Breath You Take” by The Police, and “You Don’t Mess Around With Jim” by Jim Croce appear in past seasons of the series, but none took as much of a hold on the public as Bush’s song did, although “You Don’t Mess Around With Jim” did inspire several memes of Jim Hopper (David Harbour) dancing. It’s a wise choice for the Duffer Brothers to continue focusing on music that fits well into Stranger Things both thematically and visually, as opposed to trying to create another viral hit such as “Running Up That Hill.” Viewers will have to tune into Stranger Things season 5 to see how the musical choices in the series help move its plot and character development forward, and whether another 80’s classic jumps to the top of the charts once again.,More: Stranger Things Season 4 Ending Explained (In Detail),Sources: Collider
