Well, they are not predominately teenage girls. the most successful ohas always been driven by boys and men in the 18/24 age bracket. heavy metal, punk ,rap, and goth are almost exclusively male driven. the current crop of female pop stars, Taylor Swift,Adele and so on, are a great sign that pop is now celebrating more and more female pop stars And,as I said, they are passionate, talented and successful....and they are not all the same. their “sin” , seems to be that they make money..they also make music which will be the” folk” of their generation. give credit where it is due...please.
