Yeah, guys. 'Piece of Me' is the way Britney uses to show us the reality she lives in.
The point is that we could never imagine that a song about paparazzi would make us want to dance like this one.
'Piece of Me', produced by Bloodshy and Avant (the same producers of 'Toxic' and 'Showdown'), is a hot track that combines lyrics and rythm. All that problems that Britney used to live, now are together in one song, and that's why it's so special. Miss B realizes how important she is, by saying 'I'm Miss American Dream, since I was 17'... and she continues being Miss American Dream.
