Stadium PA songs are the ones that come over the loudspeaker between plays, not for one kid running out of the tunnel but for the whole crowd. The defense lines up for a big third down, the operator hits the button, and a few thousand people start the same chant without being asked. The best ones are wired into your memory before the first note finishes.
That is the job here: short, loud, and impossible to mess up. A stadium song needs a hook the bleachers can carry on their own, the stomp or the shout or the singalong that fills the gap when the offense is trying to hear the snap count. Get it right and the home crowd turns into a real advantage the visitors have to play through.
