The band's recording of the Game of Thrones original track makes Florence the only artist to be featured in the final season of the HBO series. 

Florence + The Machine's cover of 'Jenny of Oldstones' was played during the end credits of Episode 2 of the eighth and final series of Game of Thrones. 

The track was written by Ramin Djawadi, Dan Weiss, David Benioff and George R.R. Martin, and is an adaption of a song mentioned in the novels on which the series is based. Florence recorded the song after being approached by Benief and Weiss - the show's creators and longtime fans of Florence & the Machine. 

Speaking of the track, Florence said: “When I first heard the song it sounded like a Celtic lullaby to me. Celtic music has always been in my blood, so I felt like I could do something with it."
