The song plays on many levels, talking about making great sacrifices for the one true love, as it has always happened in history and might take shape in the present as well through the only two Targaryens left.

Just like how Duncan left his throne for Jenny, the assumption that Jon or Dany might do the same for one another, now that Jon is the rightful heir to the Iron Throne and Dany is well aware of that fact, bringing the Azor Ahai prophecy to light as well. Well, what does this piece of information have to do with what's going on right now? A lot apparently! The song directly relates to Duncan's love for Jenny, Rhaegar's love for Lyanna and Jon and Dany's love for each other. Duncan happens to be Daenerys's uncle and the Mad King's elder brother, making him the rightful heir to the Iron Throne. The song is primarily thought to be about 'Jenny of the Oldstones', a girl Duncan Targaryen was madly in love with. The song is taken directly from George RR Martin's book: The Song of Ice and Fire and it connects to the larger scheme of things in the storyline. The quiet and unassuming Podrick Payne steps up to the occasion and belts out an old time classic called 'Jenny's Song'. Jaime knights Brienne of Tarth, while Tyrion fills everyone's cups with ale, requesting someone to sing a song. Greyworm and Missandei are making grand future plans to visit Naath after the war is over and a bunch of people are sitting around the fire warming their emotions and indulging in some worthy banter and storytelling. While Arya wants her last night in the arms of the man she fancies, Sansa warms up to Theon after he chooses to fight against the dead. The episode is all about bidding final goodbyes in Winterfell before the eventual fate is faced the next morning, or so the mighty men and women seem to believe. Just like how Podrick's song did in episode 2 of season 8: A Knight of the Seven Kingdoms.

Usually, the themes and end credit songs are something to always look forward to as they tell us a lot abbot the standing structure and theme of the particular episode citing incidents of historical importance. 'Game Of Thrones' always pays great emphasis to the soundtrack, the songs and the music that become a part of the show somewhere or the other.
