I have been unable to sync music and have tried drag and drop method, but iPod puts in a "lost and found" folder, so I cannot see to play it. It worked just fine until apple changed without warning! I have 120gb iPod, and love it, but this is totally frustrating! My iPod shows in the Music (formerly iTunes) app, but when I hit "sync settings" button, it does nothing. When I did the drag and drop method in finder, the new music I had added in this way did not show up in "Music" at all in the window with list of stuff I have on my iPod. I wish I could revert to the old OS so I could sync all the new music I just bought!
