Any release on the public airwaves, i.e. radio play, is an intentional release of the waveforms of music into the public domain and cannot be protected by copyright. If this is done at least once, the sounds themselves are transferred to the public domain. Its the same as a person reading a copyrighted book on a streetcorner, the sounds of the words cannot be subjected to copyright, but the book as a work can be. You can however copyright the whole CD as a artistic work, the graphics on the CD, the case it came in. One cannot reproduce or counterfit the CD in toto without violating the copyright. Therefore music sharing of the waveforms of previously aired matererial is beyond copyright protections.

Therefore music sharing of the waveforms of previously aired matererial is beyond copyright protections.

Or rather, sharing of the waveforms as previously aired is beyond protection.
