In an era where pretty much anybody can pretty much use anything for their own use, copyrights are really not holding much together anymore. When people can zip your material, use it on their own You Tube videos without permissions, rappers sample tracks, I don't know how much copyrights are even valid anymore.
Another fight that is seemingly being lost.

I have a friend who just got her copyrights registered from the Library of Congress this week. She filed them three years ago. They are backed up a minimum of two years to file copyrights, patents, etc.
