The album -- Amos' ninth studio release -- includes a track called "Yo George," in which she takes U.S. President George W. Bush to task for his policies and particularly the continuing military action in Iraq.
"I think that if you're going to call (the album) 'American Doll Posse," Amos said, "then you have to tackle what America is and where it's being led. You shouldn't equivocate."
Amos said the song was inspired by a Bush visit to England in 2006 when he greeted British Prime Mister Tony Blair with the salutation "Yo, Tony!"
