I don't remember anything other than genres / types of music being mentioned in the magazines.
But I do remember some list going round of music that was deemed unacceptable for various reasons, some seemed bizarre and many relied on "hidden meaning" to songs:
Simon and Garfunkel's Bridge Over Troubled Water? Drugs ...
I can see someone on the platform mentioning specific artists if there was a local segment, but I doubt the WTS would open themselves up to e sued by anyone, and they like to be vague on things.
