Right, so this has an incredible sound quality (with the right headphones, even better). I really love the way it looks, and I can fit thousands of my music on it. But it has a pretty huge problem that seems to be very common upon these iPods. So the problem lies with syncing, the very first time I synced, it worked, everything got on there fine. The next time however? It seemed to be working, it said syncing song blablabla out of blablabla, and then it finished. I disconnected my iPod from the USB, and turning it on I noticed that I had no music...
