Cover art for Power and Control lyrics by Marina and the Diamonds

I think Marina is tired of being taken advantage of, dropped, used, or neglected. The man doesnt contribute to the relationship as much and thinks he's hot stuff. So she has become so tired of being treated unjustly in love, so this time around, SHE wants to be the one in control of things, to make sure she doesn't get hurt.

My Interpretation
