According to Fennell's Billboard interview, the final song had originally been "I've Had the Time of My Life" from Dirty Dancing, which she said "was funny and it was kind of anthemic and kind of air-punchy, but it also undercut the emotion a little bit." Once she heard "Angel of the Morning," the director had an immediate visceral reaction to it. In essence, the lyrics speak to victimhood and sinners, painting Cassie as the angel up in the sky descending justice upon the men who harmed her and her best friend. Moreover, just like all of the songs in this movie, there is a lighthearted tone to this one that makes the final act darker, more twisted, and even sweeter to watch.
