Quote - You could still be sued on top of that, should the artist in question have the  money to do so.  They don't have to win the lawsuit in order to bankrupt you with legal fees.

In the US, this would only apply if the copyright is registered, which most people do not do, assuming that because copyright is automatic, registration is unecessary.  Registration of a copyright is required in order for a U.S. citizen or resident to file suit for infringement.  Placing your own statement "copyright 2011" within the file or metadata does not constitute registration.  Actually, the copyright office has streamlined the registration process and it can be completed on line.  Naturally, there is a fee.
