Four years after Back to Basics, Christina Aguilera is ready to conquer the charts once again with Not Myself Tonight, the lead single from her upcoming album Bionic. Written by Ester Dean (Drop It Low) and produced by Polow da Don (Forever, Patron Tequila), no wonder Not Myself Tonight sounds like an absolute club smash. It even has the same "1,2,3,4!" as Chris Brown's Forever. I was hoping for more 'touchy-feely' tracks like Hurt. Not Myself Tonight is great as a song, but I don't see it as THE single after her hiatus. Xtina described Bionic as something "completely different" from her past LPs. Well, whatever the outcome of this record is, her undeniable vocal ability is sure to show.
