I never suggested that a letter was the way to go only that some folks use that method. If you have a song posted at SoundCloud or soundclick or reverbnation or other such sites then in a court of law the infringer would have to show similar evidence of their "ownership" that predates yours or hire a Russian hacker smile

However, if I were writing for commercial interests I'd register them...or at least I would at the point somebody showed any interest. I was only suggesting that there are alternatives ways of recording your date of ownership that are viable but perhaps nowhere as seamless as "real" registration.

Heck, at my level I'd be gobsmacked and flabbergasted and flattered if someone attempted to appropriate one of my tunes!
