I suspect it's a side-effect of being good with metre, but my mind has the annoying habit of getting two songs in the same metre stuck in my head at once.
Well, he left Kentucky back in forty-three
And he didn't leave much for my Maw and me
He come up with a knife, and cut off a piece of my ear.

But I busted a chair right across his teeth,
And I left that day with a lunchbox full of gears.
