1. What poor picks to play. 2. It makes absolutely no sense. You play the "fired-up" music when the offense is out there and the lame calm music when the defense is out there. You want the defense pumped up, play the loud crap when the other team has the ball, like the NFL. You want the offense to take their time and make good calm decisions, not have fast tracked loud crap so they can't hear each other.
