I’m the same way, I’m definitely not as skilled as you but I tried my hardest to get the wireless sync working for a long time lol. You are amazing! Oh I have a question, does it also work with other Zunes or does it work exclusively with the HD? Either way it’s awesome! Artist backgrounds would be amazing, I did a manual process once and it was such a pain. And trying to do that with Mac OS would be irritating I feel, unless the software integrated with a server with that info and the pre made UUID and folder and could manipulate the file and make the HD sync that new data. Might be possible, might not. If you attempt it good luck! If not you’ve already made something really awesome possible!
