song with simile

I'm Like A Bird- Nelly Furtado

I'm like a bird, I'll only fly away
I don't know where my soul is, I don't know where my home is
(and baby all I need for you to know is)
I'm like a bird, I'll only fly away
I don't know where my soul is , I don't know where my home is
All I need for you to know is

The title is a simile because she is comparing herself to a bird.
