Cover art for Bird Song lyrics by Florence + the Machine

I think this song is about you doing something terrible to the one you love and wanting no one to know, but someone found out what you did and your worried that they are going to tell everyone including the person you love, so you do everything you can to make that person keep their mouth shut, but the guilt drives you so mad you cant help but blurt out everything you never wanted to tell.
