My ipod shuffle will not autofill from any of my playlists or the library. At the bottom of the Itunes window it says that i am using 380MB of song memory, but itunes shows nothing on the playlist for my ipod shuffle. why is this??? Even though i have no songs on the playlist, when i disconnect the ipod shuffle from my computer and play with my headphones, i am listening to songs that i did not "update" to my ipod shuffle. Hope this makes sense. Please help.
