"Why is there a "do not disconnect" logo on my screen"に関する回答@debbie Make sure you use iTunes, and connect your iPod. Select your iPod in the navigation panel on the left, Devices section. Now use the Music button in the top menu. Select to synchronize only "Selected playlists". Only the tracks used in the selected playlists will be synced to your iPod. The other tracks in your music library will not appear on your device.
