Copyright for Music and lyrics

A composer or artist has copyright to their work upon completion to their work. The Author has copyright protection for their work up to 95 years and 50 to 70 years after death. The current year for public domain in the US is 1922. Having copyright to music means you have the rights to print, copy, publish, and sell your work. The difference between Public Domain and Proof of public domain is you can’t copy music, publish, or rearrange in a Public Domain without proof in that it is in a public Domain. Proof of public Domain means you have proof that the music is in a public domain. Rules for copyright for music and lyrics are if you do not have copyright to music you cannot copy, publish, perform, or copy the music without permission from the author. A case of copyright infringement is the case of Michel Bolton vs. Isley Brothers. The Isley Brothers sued Michel Bolton lifting parts from their original song of the same name. http://www.mpa.org/copyright_resource_center/copying#copyright http://www.pdinfo.com/copyrt.php
