I may be able to offer a unique perspective on this subject, the listening to rap and pop starts from an early at school. Children have to be in with the latest fashions and such, therefore they all buy the same clothes, have the same hair styles and listen to and buy the same music....
'Yo sarah have you heard Britney Spears latest song (crap -sorry!)' 'yes i have its cool'.
There you go. This culture continues into their teens then to adult-hood. 'Chuckle, Eminem just said s*!t' oh really but can he play the guitar?, can he play like jimmy page? Methinks NOT!
I was one of these kids,but i started listening to sumin a friend had on ( i think it was a sabbath track?) and i was hooked, i started to get some CD's, purchased an axe and have never looked back!

So all of you out there, if i catch you listening to Ms Spears or N-s*!t i will come round ya place and beat the living c£*p out of you then shove the CD's up your a$$!

Keep it real axemen!
