It's either a Mayer improv or a Death Cab tune

Every little thing's gonna be alright.
Every little thing's gonna be alright.
Oh every little thing's gonna be alright.
What can I control?
What can I control?
Nothing. Nothing.
I might as well fall.
I might as well let go.
I might as well fall.
Stop holding on
To every little thing
Every little thing..
