It's interesting to me for the same reason, as a writer. I've never had a song lyric where I felt like profanity was necessary, however that's been a harder tightrope to walk in short stories. There have been plenty of times where I was writing dialogue and I thought, "I know my character would be cussing right here--but I don't want to write it! But I knooowwww he'd say it...But!" And so on, haha. You've caught on to exactly why I prefer refraining though. Regardless of how you intend a word, you don't know how someone else might take it. What you mean as a joke could be taken as a derogatory slur by someone else.
