[2] "Broken Heart Thing" was originally written by James McNair, Lalo Guzman, and Michael Tyler, and was intended to be a solo sung from the male perspective about the aftermath of breakup.

[3] Merlo heard the demo of the song and admired how it portrayed the adjustment of life after the end of a serious relationship as "something akin to a grieving process" and "grasped that idea really well".

[4] Merlo initially wrote a new bridge for the song, before she and her producer Zach Crowell decided to turn it into a duet told from both a female and male perspective.

[5] Madeleine O'Connell of Country Now positively noted that Merlo and Lynch "[offered] a string of mesmerizing harmonies," stating that the two artists "[came] together to show the devastating effects that a recent heartbreak can have on both parties".

[3] The official music video for "Broken Heart Thing" was directed by Jack Owens and premiered on YouTube on August 9, 2024.
