Changes

}}'''"You Know What You Are?"''' is the second track from 2005's ''[[With Teeth (halo)|With Teeth]]''. It is a very aggressive and upbeat song, featuring a gang-shouting chorus and heavy guitar tracks. A remix of this song by [[Clint Mansell]] appeared on the ''Doom'' soundtrack, and played during of end credits of that movie. The title strongly resembles a track on the "''[[Head Like A Hole (halo)|Head Like A Hole]]" '' single, entitled "[[Head Like A Hole (song)|You Know Who You Are]]."

The lyrics of the song appear to be commenting on a person's inability to change for the better, evident in lyrics such as "You can dress it all up you can try to pretend / But you can't change anything in the end.", and "Don't you fucking know what you are?/Go on get back to where you belong.". Many interpretions of this song often overlook the possibility that the "you" to which [[Trent Reznor]] refers, may in fact be himself.
