The album is not bad at all. In fact, it's my favorite album of hers.
We are already confirmed to be getting 4 singles, because Britney said "Alien" will be added to the Vegas set list on the second set of shows once it's a single, and it's not even in the running to be single #3, so that leaves the 4th for Alien.
I'm here for Till It's Gone, It Should Be Easy, and Tik Tik Boom as the third single. Any of these and I'll be happy!
