Those terms and conditions some of the frum cd’s state are a meaningless unenforceable joke that has no force. Can’t play in public? What if they stick a term in there that you have to mail the producer a $50 check every year you play it?
And the “rent” idea is even funnier. Do they really believe that if I am negligent with that cd and it gets stolen or broken for example that I am liable to the owner? That I can’t resell the cd to someone else since I don’t own it? Neither the seller nor the buyer really mean to rent this cd and that’s what matters, regardless of what it says on the cd.
