Copyrights are a sticky issue. It gets stickier when you realise that mudcat is international. When I start a thread about US copyright law it won't apply directly to many of us. Likewise other countries that have representation. The above case is swiss law, and we don't know what US law (or canadian or austrilian or irish or...) law will do about the same situation.
I mention the above because copyright law changes all the time. Currnetly copyrights are good for something like 100 years after the authors death, up (rectoactivly, which I think is on shaky constitutional grounds but I'm not sure) from 75 a couple years, up from 25 years, up from 50 years total (no after death clause). Now I agree that authoers need protection for their works. I'm concerned about those who think copyrights should be forever. The point is to watch congress, the longer copyrights last, the longer we have to wait before we can legally share the songs we love.
