Sex sells and we can expect it to never end.
Take the all female band name "PussyCatDolls" and their latest single, "Buttons" for example.
MYGOD! This mother told me that her young daughter of 8 yrs old, was singing to this song but had no clue what the lyrics meant. Yeah, another year or two, she'll know what "buttons" that band was singing about.
I think that it's best to educate your kids about sex as parents rather than have somebody else educate them.
Times are certainly changing because when I was younger, this kind of music wasn't really available or perhaps, I never really paid attention to the whole pop culture.
Ah, classical music will be the ONLY music kids can listen to....
