After your device is connected, i Explorer will display its Device Overview screen.
You can also access your music by clicking Media Library through the sidebar on the left.
Problem: Using manual i Pod update, Playcount and My Rating (i.e.) will not be synchronized between i Pod and i Tunes.
To fix this problem, you can use synchronization BUT...
Your i Phone, i Pad or i Pod will begin the metadata recovery process which may take several minutes depending on how many music tracks you have. Only the metadata, ratings and playcounts of existing tracks in i Tunes will be updated from the information on your i Device.
Once the process is completed, you should see all of your tracks in i Tunes have been updated to display the ratings and playcounts that are on your i Phone, i Pad or i Pod.
