In May 2015, a few fans met Del Rey and she revealed to them that a song off her record would be titled "Swan Song".
After images from the booklet that accompanied Honeymoon's physical release leaked, some fans of Del Rey took to social media to express their unease at the line "and I will never sing again". Many worried that the line, along with the title of the song, it's placement on the track listing as the penultimate track before "Don't Let Me Be Misunderstood", and the inclusion of the song "God Knows I Tried", in which Del Rey sings about resenting her fame, would be a literal representation of the final song of her career and that Honeymoon would be Del Rey's last album. However, these concerns proved to be unnecessary, as in September 22, 2015, Del Rey told radio presenter Huw Stephens on BBC Radio 1 that she had begun the writing process for the follow up to Honeymoon "a few months ago".
- The opening of the song samples vocals from "High by the Beach".
- Working hard is also mentioned in "Wait for Life".
- The term "Swan Song" refers to an ancient Greek myth that said that swans would sing a beautiful song right before they die.
- The phrase "the world can change in a day" is similar to "it's funny how some things just change in a day" from demos 1 & 2 for "Lust for Life".
