Gibbs is also a no rap ballpark. We only play music before the game, in between innings and after the game (no player intro music). The players can request songs to be played if they provide me a copy of it and I listen to it beforehand (I will not play it until then). As long as it meets reasonable family/school parameters of language and decency plus is entertaining, it can be played. My thoughts about this are, if you can see that the crowd is relaxed and the players are singing or moving to it, you have to be doing something right.
