Christina Aguilera has finally release her latest single titled "Not Myself Tonight".It is the lead single from her forthcoming fourth studio album, Bionic. It's totally awhole new site of Christina and very futuristic plus the complete opposite to the songs from Back to Basics. But one thing about this song is that its kinda Britney in it. The starting maybe a little blend but as the vocals kick in the beat gets better. I'm sure it'll be a number club song. Here's the song for you guys to enjoy.
