A new Florence and the Machine song debuted on last night’s episode of 'Game of Thrones.'

Florence and the Machine could be heard during the closing credits of the episode singing 'Game of Thrones' original song "Jenny of Oldstones."

Podrick Payne sung an excerpt from the song earlier in the episode while he was by the fire with Brienne of Tarth, Jaime Lannister, Tyrion, Davos Seaworth and Tormund.

"Jenny of Oldstones" was written by Ramin Djawadi, Dan Weiss, David Benioff and George R.R. Martin. According to Westerosi folklore and the 'A Song of Ice and Fire'books, the song tells a sad story of a prince having to choose between true love and the Iron Throne which leads to lots of bloodshed. Sound familiar?

Florence is the only artist to be featured in the final season of the hit HBO series. She recorded the song after being personally approached by the show’s creators, longtime Florence fans David Benioff and D.B. Weiss.

Benioff and Weiss said in a statement released after the show

“We’ve always been huge fans of Florence’s music, and the Season 2 trailer with her song ‘Seven Devils’ was possibly the most powerful we’ve ever had. So the opportunity to hear her otherworldly voice on our show was always at the forefront of our minds. We’re still pleasantly shocked that she agreed to sing ‘Jenny of Oldstones,’ and we’re in love with the result.”

“When I first heard the song it sounded like a Celtic lullaby to me,” says Florence. “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 honored to be a part of the final season.”
