“Agatha All Along” borrows its choice of “Seven Devils” as trailer music from “Game of Thrones.” In 2012, that series used the song in the trailer for its second season. The title of “Seven Devils” can be seen as referencing the seven deadly sins; Westeros has those in abundance and they’ve been the downfall of many playing the game of thrones. The song’s ominous lyrics about coming destruction (such as “I’ll be dead before the day is done”) fit well with the season’s main conflict, The War of The Five Kings, while the mythological allusions reflect the looming threat of the White Walkers. Lastly, season 2 is when the show introduces the red witch Melisandre (Carice Van Houten).

Welch, meanwhile, is a fan of the Showtime horror series “Yellowjackets” — “[It] appeals to me because of my fascination with all things culty, but also it portrays the violence of the hormonal shift of girlhood so well,” she once told Bustle. “Dream Girl Evil,” featured on Florence + The Machine’s 2022 album “Dance Fever,” was even inspired by “Yellowjackets.” During the show’s second season in 2023, the show repaid the compliment by recruiting Florence + The Machine to cover “Just A Girl” by No Doubt for its trailer. “Yellowjackets” season 2, episode 7, “Burial,” also featured the Florence song “Free” and played “Dream Girl Evil” over its end credits.

“Agatha All Along” isn’t even the only Marvel series to needle drop Florence + The Machine. “Guardians of the Galaxy Vol. 3” concludes with “Dog Days Are Over,” from the band’s 2009 debut album “Lungs.” That song, about celebrating once you’ve climbed out of a rut, is much more optimistic than “Seven Devils.” Like different corners of the Marvel Universe, Florence + The Machine’s music can be both uplifting and creepy.

“Agatha All Along” debuts on Disney+ on September 18, 2024.
