for listening on AOL Music on November 30, 2007 and was later released as Bittersweet World's lead single on December 11. Although the song received a positive reception from critics, it became Simpson's first single to not make the Billboard Hot 100 chart. This was attributed to the synth-pop song being too outside of Simpson's traditional rock sound to resonate with her core fans.
