This type of censorship BS didn't just stop with worldly music. NO.
As a child of the 80's, not only could I not have or listen to worldly rock music, but I was forbidden from wearing any clothing whatsoever that bore large logos. This was considered worldly, materialistic, or having a "showy display of one's wealth." No t-shirts with pictures of anything on them either.
This meant up until I was about 15 and old enough to get a job and buy my own clothes with my own money, I was forced to always have a very cheap, "Generic" look at school. You can guess how this went over, and how it crushed my self-esteem and effected my demeanor. My parents were also the typical "cheap" JW's, so especially as a child this meant shopping at the local Goodwill and thrift shops. So not only generic crap, but used out-of-style CRAP. I was perpetually pissed off at this treatment, especially because we were more middle-class, and THEY didn't buy their clothes at Goodwill. (though they did dress cheap and generic)
As soon as I was old enough and had my own money, it was on. I bought the clothes I wanted, I bought the music I wanted, and anything else. Fugg 'em! I've never shopped or subjected my son to a Goodwill store either. (only high-end thrift store, of which there are a few around here with damn nice stuff when he was a very small kid)
I was also not allowed to have any posters on my wall of anything other than nature scenes. Everything else was considered idolatry, false idols. Growing up a JW was INSANITY. Everything was "No." No friends that weren't JW's, no riding the bus, no school activities, no afterschool anything, no sports, no going to friends houses, no going outside of my own yard, no going to the mall without parents, no going to the movies no NOTHING that wasn't JW-related. This is how I grew up. My parents NEVER took me to see a movie in a movie theater. I was 16 yrs old when I went by myself to a movie theater the first time. I was so excited! The isolation I was subjected to was prison-like frankly. Gee, any wonder I was resent this oppressive cult now? Big mystery.
