"The anti-heroine must surely be the main character, who is a baddie, rather than just any old nasty female who happens to have any sort of walk-on part?"

MtheGM to clarify my initial query, I'm particularly interested in 'subversive' or non-traditional (ones who might traditionally be considered negative) female figures, who play a key role in the plot. Such a figure might perhaps be 'shadowy' and not feature as the central character or protagonist, but without her there would be no story to tell.

Otherwise, I'm happy for people to throw up any songs they feel describes interesting subversive female figures. It's been fun to read through the lyrics of the songs suggested so far, and compare these characters!
