Simpson's most recent music came in February 2020, when she included six songs in the audiobook for her memoir, Open Book. Those tracks were Simpson's first in nearly a decade, as she had last released Happy Christmas in 2010.
"The music is actually everything that inspired me to get sober and write the book," she said. "Because I realized when I was going down into my studio, even though I was in the comfort of my house, I had to drink to numb the pain that I was about to experience to write."
"Songwriting takes me to an honest place, and honestly, I was in a dark place," she added in the book. "I just didn't know it until the words came out of me."
