Query: What is she thinking?

Fighter? Maybe, but the sound of the song is wrong. Christina Aguilera is a terrible rocker, if you call her that! Rock is something she's weak at singing. Just because Dave Navarro plays guitar on this doesn't make it good. It makes her a rock sellout. Avoid at all costs unless you want to see Dave Navarro go pop.
