“Not Myself Tonight”
"Not Myself Tonight" is the debut single from Christina Aguilera's fourth studio album, Bionic. The tune was intentionally different from anything she had previously recorded: "I was able to explore and create a fresh, sexy feel using both electronic and organic elements with subject matter ranging from playful to introspective," the singer explained. "It is something I don't think anyone will expect." The accompanying video was a direct homage to "Express Yourself" by Madonna, who Aguilera credits as being an inspiration.
