Here at CDO high school, they use the sound system professionally. It is great and makes the game more enjoyable. They are state champs, normally. I forget if they do walk up music, but between innings the guy is great. He uses an ipod.
I know bama and probably every other ncaa team would disagree with most of you old farts.
Is that a valid comparison comparing a team of 10 or 12U players showing up at one of 8+ fields blaring their boom boxes in competition with all of the other boom boxes as a team does pregame with a college team pregame where spectators are in attendance and so an entertainment enviroment is acceptable? Have you seen cases where bama played their boombox as every other NCAA team played theirs during pregame?
