Some days feel so heavy
They come when I'm not quite ready
I get to feeling useless
But I can see right through this
I'm gonna let the song in my head ring

It feels like the world is collapsing
But I already know it's gonna happen
I'm gonna hold on tighter
Yes, I'm a lover, but I'm also a fighter
The song in my head keeps me clapping

'Cause I've got a song, and it must be sung
Every day's a war, and it must be won
Whenever I feel like I'm comin' undone
The song in my head keeps me marching on

The world's full of bad news bearers
Talking heads talking 'bout terror
Sometimes I feel so useless
Like nothing I could do would ever improve it
But I could make the world a little better

You tell me that you're worried 'bout tomorrow
You talk like all the time you've got is borrowed
Like you're livin' on credit
But you keep singing, honey, you can bet it's
Gonna sing it through tomorrow

With a song, and it must be sung
Every day's a war, and it must be won
Whenever I feel like I'm comin' undone
The song in my head keeps me marching

With a song, and it must be sung
Every day's a war, and it must be won
Whenever I feel like I'm comin' undone
The song in my head keeps me marching on
