Why do you need music to get you fired up on 3rd down?I really don't understand where you're going with this. We either blare Rick Ross/Crime Mob through the loud speakers on 3rd down, or.... the band. Which one is going to fire up the fans and players more? Pretty obvious answer because it's what we already do. It's not going to please everyone, that's fine.
If the 3rd down game situation itself isn't generating sufficient adrenaline and motivation for the players on the field, and they need loud noise to motivate them, then there are some serious problems...
