It varies significantly from country to country; some treat sound recordings differently, and others don't. The shortest a sound recording copyright is valid is 50 years from creation (the minimum required by Berne); the longest is the life of the creator plus 100 years (Mexico).
I'm not aware of a circle P having any significance in medicine. It is commonly used as a copyright mark for recording [similar to circle c (C) - copyright, and circle r (R) - registered]. I believe circle p - (P) - is meant to be performance recording copyright or phonograph copyright (or something similar)Also, (P)i is the symbol for a phosphate group in cellular respiration. The phosphate group is added to ADP to create ATP.The formula is ADP+ (P)i -> ATP+ H2O
'p' inside a circle means 'protected by copyright law' and you are not allowed to reproduce it without permission from the author
It is the copyright of a song. For example you might find the circled P and next to it 2012 Atlantic Records
On music mediums, it's the phonograph symbol, which is a lesser-known variant of the copyright symbol.
The symbol is the letter "P" with a circle around it, like this sorta: (P) The "P" stands for production, dont be asking me why, because I dont really know, to me, its a mystery... :P
A P in a circle indicates that it is a sound recording that is under copyright protection. The P stands for phonograph, but it has been interpreted to mean any means of recording sound. That also means it cannot be used without permission. The media is the property of the holder and cannot be changed to another media.

It is the symbol that indicates copyright. Copyright means the owner has control of the item and can determine how it is distributed. The Constitution of the US establishes the Copyright Office and the protection of these rights. International Copyright laws are getting better and are being enforced globally. © This symbol means that the item is copyrighted. For example, if a book is copyrighted then the writer of the book owns the rights to the book, so that if any part of it is copied or used eleswhere without the copyright owner's permission, that is against the law, and the person who breaks the copyright can be prosecuted. Normally it means that whatever it is referring to is correct.
