Lily Allen - "Hard Out Here"
I have no shame in saying that I love Lily Allen and, seeing as her last release was back in 2009, her return is long overdue. With “Hard Out Here” she points (to quote Pretty Much Amazing) a "giant foam middle finger to the music industry’s institutionalized sexism." I would go into more detail about the song but all you really need to know is that the chorus goes "Forget your balls and grow a pair of tits / It’s hard out here for a bitch."
