what you have to do (no extra programs needed) is to set itunes to "copy all music to music library", you plug in the ipod and enable disk mode (make sure you do not overwrite the music on it) then in my computer you enable view hidden files and folders, go into (if F is the drive that your ipod is plugged into) F:\Ipod_control\music and select all, right click and set them to non-hidden, then drag the music into itunes
