To quote Keith Richards "if it's too loud, you're too old"
In all seriousness though I haven't been to an arena yet that I've felt the music was too loud or interfere g with the experience. I have, however been to plenty of games that who ever was selecting the music ought to have been hung from the catwalks. I'm not saying the music needs to be blasting ear drums out, but some good loud music helps keep the energy level of the crowd up during long breaks in the action
