Did you know that Prince’s song “Darling Nikki” was the catalyst for the parental advisory sticker? Yes, Tipper Gore, wife of then-Senator Al Gore, purchased the album Purple Rain a gift for her 11-year old daughter. She was quoted as saying in her book, “When we brought the album home, put it on our stereo, and listened to it together, we heard the words to “Darling Nikki”: 'I knew a girl named Nikki/Guess (you) could say she was a sex fiend/I met her in a hotel lobby/Masturbating with a magazine," she recounted. "The vulgar lyrics embarrassed both of us. At first, I was stunned, but then I got mad! Millions of Americans were buying Purple Rain with no idea what to expect. Thousands of parents were giving the album to their children — many even younger than my daughter.”
