If you watched Sunday’s episode of Game of Thrones, you heard some brand new Florence + the Machine.

Showrunners David Benioff and D.B. Weiss asked the songstress to write a song encapsulating the emotion of the final season. “Jenny of Oldstones” was first sung by Daniel Portman’s character, Podrick. The studio version played during the credits.

“When I first heard the song it sounded like a Celtic lullaby to me,” Florence Welch said in the statement. “Celtic music has always been in my blood, so I felt like I could do something with it. The magic and ritual in Game of Thrones, not to mention the costumes, have always appealed to me. I am honoured to be a part of the final season.”
