strip club music selection

I've noticed that most local strip clubs here in Indianapolis play almost nonstop rap music. This in a city where the majority of customers and dancers are not black. I've talked to my favorite dancers about this. A lot of them don't actually listen to that type of music themselves. The last five I talked to had the five following favorites: White Stripes, Marilyn Manson, The Doors, Nirvana and Bob Seger. So the club dj is by no means playing what the girls like. I've talked to the girls and they also tell me the big spender types aren't really big rap fans and that rap actually attracts the type of customers into the club that the big spenders don't want to be around. So what exactly is the purpose of this and how has it come about? The girls seem perfectly capable of dancing to other types of music when it's played so they don't have to play rap for the reason that it's the only type of music that can be danced to.
