The song "Houston Train" by Houndmouth tells the story of a person's journey and their encounters along the way. The lyrics describe receiving a postcard and money from someone, who promises to meet them in Memphis if they bring them pills. The protagonist gets high and dry for far too long, but eventually decides to take a gypsy train to Houston. People refer to the protagonist as a wild card and a fool, but they assure them that they will bring them their money if they help them return home. However, they end up being robbed of all their cash. Despite this setback, the protagonist cleans up their life, gets a steady job, and stops running from the law. But even though they have changed for the better, the gypsy train to Houston continues to haunt them and won't leave them alone. The song explores themes of longing, redemption, and the consequences of one's actions.
