Country Song Upside-Down

I found a song upside-down
A country song like a trout
Dying sky and water
Rainbow flickering out

Inside a dark cabin
The more moonlike I become
Rounding all of my edges
'Cause I'm worried
Can't be sung

This is the gist
It goes
Like this

I found a song upside-down
A country song without a doubt
Dying sky and water
Rainbow flickering out
