A- // We Can't Stop // Miley Cyrus

• Women as empowered
• "We run things, things don't run we / Don't take nothing from nobody"
• Women not in relation to men (but it's not specifically about women either)
• Women objectified, but rejecting those who view this negatively
• To my home girls here with the big butt / Shaking it like we at a strip club / Remember only God can judge ya / Forget the haters 'cause somebody loves ya
• Just in case you thought these ratings were trying to just be kid-friendly, there are references to ecstacy/MDMA and probably cocaine

A // Roar // Katy Perry

• Portrays women as powerful
• "I got the eye of the tiger, a fighter, dancing through the fire / ‘Cause I am a champion and you’re gonna hear me ROAR"
• Not about women only in relation to men (it could be about anyone)
• Not objectifying women
• No name calling

I would give this an A+ if it were particularly about women, but if a man sang this song, it wouldn't be. 

D // Blurred Lines // Robin Thicke ft. T.I. & Pharrell

• Objectifies women
• "What do they make dreams for / When you got them jeans on"
• Name calling
• Bitch
• Is about women in relation to men
• Not many women can refuse this pimpin'
• Other offenses:
• I'll give you something big enough to tear your ass in two
• Could be empowering
• tried to domesticate you/But you're an animal.../That man is not your maker
• You're a good girl.../You're far from plastic
