Guest Jon - technically, yes, and many lyrics sites have been closed down by the music publishers, but happily the Mudcat is in the USA where there is a better chance of running a "fair use" defence and if push comes to shove it could take down all truly copyright lyrics leaving only folk songs.

There might be an argument about the pernicious practice of US interests seeking to "copyright" works in which copyright has expired by registering them with some foolish variation at the Libarary of Congress.

To be accurate, however, since copyright arises automatically upon creation, it is not truly possible to "copyright" something, although it is possible to dedicate something into the public domain (or abandon the copyright in it) (as, arguably, Ghandi did when he said "I have never copyrighted anything").
