music

my favorite music as stated is christian rock, i don't really care for others genres because i don't get the point really, if its not for praising God whats the use, i also don't get what you do at concerts, at a christian concert you can sing along, dance, raise your hands, and just full out get into it and injoy his presence, but at a rock concert lets say, what is the point, i really dont get it, do you go to get moshed? hopfully someone can answer my question.
