[verse 1]
right now, i feel like a bird
caged without a key
everyone comes to stare at me
with so much joy and reverie
they don't know how i feel inside
through my smile, i cry
they don't know what they're doing to me
keeping me from flying
that's why i say

[pre-chorus]
i know why the caged bird sings
only joy comes from song
she's so rare and beautiful to others
why not just set her free?

[chorus]
so she can fly, fly, fly
spreading her wings and her song
let her
fly, fly fly
for the whole world to see

[outro]
she's like caged bird
fly, fly
ooh, just let her fly
just let her fly
just let her fly
spread the wings
spread the beauty
