I honestly can't speak to the national differences between implementation of copyright laws. The key benefit to all of us is that they have subscribed to international copyright conventions.In the United States,
registration of a song costs you 35¢ apiece if you register 100 songs at a time. (The public servants at the Copyright Office will thank you.)
And it means that US Marshals
can actually show up to enforce your rights. In the early 90's I worked for a software company who fired a Vice-President who then used them to exact his revenge. He reported them for having too many Word Perfect® licenses. (Does anybody remember Word Perfect? Does anybody want to??)
Nevertheless, one day the US Marshals showed up. They were actually very nice people. All of us just went out for an early lunch and let them "do their thing."
Of course, the people who are in the business of [legally ...] buying and selling music – and ensuring that all of us get paid
for what we managed to sell them – have zero
interest in experiencing a visit from US Marshals! So, when you go to sell your car (in the US), be sure to bring your title
number with you. With it, they can "polish their company's nose" in less than sixty seconds.
