This cut was written by Armiger, along with Bruce Wallace and Amanda Flynn. The trio told The Boot
the story of the song:
Armiger: I wrote the song with Amanda and Bruce visiting Amanda's mom in Kentucky. We were listening to all of these horribly tragic songs on the drive there. Surprisingly, all of the tragic songs had fairytale happy endings. We started talking about how things never really turn out that way. We wanted to write a parody for all those songs, so we wrote 'Best Song Ever.' It took us about 20 minutes sitting on Amanda's mom's couch.
Wallace: I had met Katie at a writers night through Amanda Flynn a few weeks earlier. She invited me to come to Kentucky with her and Katie, promising I'd get the single if I joined the retreat. Of course, I had to take her up on it. We watched Hoarders
' for 24 hours and finally thought of the idea 'Best Song Ever.' It went pretty quick. I'm pretty sure none of us though it would do what it has, but I like to call it "the little song that could."
Flynn: We started writing 'Best Song Ever' after hearing a bunch of "love gone right" songs on the radio. They were good, but we joked about writing the best song ever, and then we did.
