Cover art for Bird Song lyrics by Florence + the Machine

Am I a fool for taking this completely literally?

That she killed the bird but it sang inside her guilt to make her scream the story out. Which is what the song is - the song the bird made her sing.

(( Reminds me of that story about the kings with big ears, and only one servant knows. He can't keep the secret so he whispers it to a tree. Years later that tree is made into muscial instruments and when they play them the music is saying 'the king's got big ears!' ))
