If you're a woman and quite a mediocre singer then do a song about lesbianism or prostitution and you'll get exposure, anything else requires talent.
I'll sound like an old fogey now, I was never bothered by the lyrics in songs etc. (stil not overly) but one day a woman got on the bus with a kid (about seven years old) and he was singing the chorus of a song that was out then ##"I'm horny, horny horny horny, soo horny, horny horny horny tonight"## she'd long since given up trying to stop him, now he didn't know what he was singing about, but he had been exposed to it and perhaps it was inappropiate.
I've sometimes wondered (worthy of a question in itself) when you look at the objections to rock and roll and it's supposed lasciviousness (seems tame now) whether they were right afterall....
