Ummmm... just to be troublesome... based on Lee Wilson's (who is an attorney specializing in the music business) book "Making it in the Music Business" ((c)1995, 1999 by Lee Wilson, Allworth Press, MY, NY)...

"There is no such thing as a state copyright statue; there is only one copyright statues in the U.S. and that is a federal statute."

This stems from Article 1, Section 8, Clause 8 of the US Constitution - which grants Congress the right to pass copyright laws -
