21 Pilots, "Stressed Out"
No wonder the 21 Pilots are stressed out. They can't decide if they are singing about the stresses and insecurities of the millennial generation, or economics. This song contains references to competition, sunk costs, opportunity costs, marginal thinking, and money, among other things. You can build rocket ships or play in tree houses in your imaginations. In the real world, all you hear is "wake up you need to make money!"
