This was written by Ido Zmishlany and Scott Harris. The pair are Long Island-based musicians; Zmishlany was formerly in a band called Lion of Ido.
In our interview with Ido Zmishlany
, he revealed that he originally created a track that was upbeat for the song. Both he and Harris felt that something was not right and that the fast tempo did not match the name of the tune. So they returned to how the song first came to life and made it piano-based, "We thought that the title, 'Life of the Party,' could actually fit a song that was more like a piano ballad. It's an interesting juxtaposition."
Zmishlany and Harris worked back and forth on perfecting the song and fixed the lyrics multiple times. "There were a couple of more lyrics that didn't make the cut. The second verse got cut in half so there's a whole other verse that exists on my computer and not in reality," revealed Zmishlany.
