song to mp3 conversion can actually mean either export of 'songs' in various audio formats to MP3, in which case you have to be more specific with the file types. Or it can mean a specific .song files, ones that had been used in old versions of Mac (System 7). Some older versions of iTunes actually did support .song files, so there is the change for potential export. But otherwise we have found mentions about such conversion using modern software.
