Ashlee Simpson-Wentz's first album, Autobiography, debuted at number one in the U.S. in July 2004 with first week sales numbering around 398,000 copies. The album was certified triple platinum in September 2004. Ashlee Simpson co-wrote all of the album's tracks and described it as "very true to my emotions" in one interview, but critical reviews were mixed. Rolling Stone magazine's Peter Relic characterised Autobiography as a "mundane melange of Avril-ish brat pop and Sheryl Crow cod rock." E! Online wrote "Even if it doesn't wow you, Autobiography may surprise you." The single that preceded the album, "Pieces of Me," was one of the biggest hits of the summer in the U.S. and sold well elsewhere. However, the follow-up singles, "Shadow" and "La La," were less successful.
