In my attempting to be creative work, I've had to look hard at the swearing issue. A 'curse word" should be high impact - used as a punch to develop an idea. If it's just thrown around with no effect intended, then it ceases to matter. Imagine a language with no cursing?
Impossible. Here, in French, the swearing is all sacred Christian symbols, as until 50 years ago this was a very religious place. In English, it's bodily functions and sex we use to shock, with a few leftover religious words. Take away standard cursing and you're going to get new cursing. People just have to do it.
If someone writes a song with only church or state approved vocabulary, fine. There was no need to use taboo words. If they write songs with swearing - equally fine. Understanding their choice of words is part of understanding their message.
I really don't like censorship of songs, which is why I always buy the freely produced version.
