In conjunction with the release of her memoir, Open Book, and its accompanying audio book, the 39-year-old singer also dropped six songs, her first new music in nearly a decade.
When ET recently caught up with Simpson, she opened up about how making her new music was a cathartic experience amid her struggles with alcohol.
"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 adds in the book. "I just didn't know it until the words came out of me."
Tune in to Tuesday's episode of Entertainment Tonight for our full interview with Simpson. Until then, keep reading for a song-by-song breakdown of her new music.
The powerful anthem is one that Simpson wrote when she hit her three-month mark of sobriety.
