I've read the posting above...very informative and interesting. I understand the public performance componant to licensing for poscasts and the fact that podcasting doesnt comply with the compulsory framework set for sound recordings (hence the need to license directly from SR copyright holders...yikes). What I'm not certain about is the other end of the music publishing spectrum: mechanical licensing. Would a poscast necessitate a mechanical license or is the download of a poscast not considered a mechanical reproduction if, for example, you didnt know what song(s) you were getting with the podcast?
