Xo

Kelsea Ballerini penned this song with Catt Gravitt and Gerald O'Brien. The subject matter takes a turn from what you might expect, which is something Ballerini loves to do. "My favorite songwriting trick is writing something like 'XO.' In my brain, I thought 'This is probably going to be a love song," she told Billboard magazine. "How can I change that and find ways to twist that. As a songwriter, it's your job for the song to take twists and turns that people don't expect."
