copyThing (formerly iPod.iTunes) does real add-synchronization, even in two directions if desired. copyThing evaluates the source for songs, podcasts, videos and/or playlists that are not in the target and only adds these seamlessly, avoiding duplicates, saving your time. Unlike iTunes' "auto update/sync" function copyThing generally does not delete content in the target. copyThing can also transfer song dependend data like "My Rating", "Last Played", "Play Count", and album artwork.
