Hey ive seen obnoxious with the wrong team. I know of a local team that did the built wagon and sound system. It was totally annoying when on a 10 field multiplex you could hear the music over everyone. Kinda like short man syndrome.
I also agree with SMS90. That is a coaching issue not a music issue. The players should not adjust for the music, the music adjusts to the situation.
I have seen the new app that lets you cut 10 seconds and then it announces the players name and number. While very cool it is a little over the top for 10-12u.
What is the name of the app?
