I can't say anything about showtunes in other venues, but as far as baseball games go, I believe the players each choose the song that plays when they come up to bat. Pay attention sometime and the same song will play every time.
So I don't find it so amazing that Les Mis was blasting through a baseball park as I do that one of the players chose the overture as his theme song over all the other songs in existence. He is officially my favorite pro athlete. :)
