It's not about fun. College coaches don't get mad over the walk up music. They just turn to a feed of another game of another player they are interested in. If you'd be on the viewing side of the feed, you'd find the constant starting and stopping very irritating also.College players literally have walk up music. If a college coach gets mad over walk up music I don't think I want my daughter playing for that coach. Let the kids have some damn fun.
Ultimately, walk up music from 15-18 years old where there are livestream cameras on the back fence is a very selfish gesture since it could ultimately cost a player an opportunity to play at the next level for their dream school. JMHO (plus I've seen it happen}
Then again, today's society has become "All about me!" so just keep on keepin' on.
