Music Industry and Sex

I was watching the CMA music awards and just thinking about the discussion in class about how music videos utilize blatant sex more than anything else on TV. I mean look how much hotter Carrie Underwood got while being transformed into an american idol. The popular music industry exploits sex no matter the genre. I think constently being in the view of a camera is the cause of the focus around the sex image. This link doesnt deal with sex but addresses maybe how people can be changed by a camera.
