"Should've Been A Cowboy" is about counterfactual longing made bright enough to share. The speaker does not simply say he likes cowboys. He imagines a whole life that would have been cleaner, freer, and more heroic than ordinary adulthood: riding, roaming, campfire songs, outlaw danger, Texas Rangers, the go-west command, desert stars, and a dream carried like a prayer.

The Western references matter because they are already myth. Marshal Dillon, Miss Kitty, Gene and Roy, Jesse James, and the cowboy props are less historical claim than emotional shorthand. They give the singer a ready-made shape for the person he could have been. The music keeps that meaning from becoming self-pity. Its bright regular motion turns regret into a communal hook, so the missed life feels less like a wound than a ride everyone can enter for three minutes.
