Sometimes you may forget to back up your iTunes library while you're reinstalling your computer, or you may lose your iTunes library due to computer crashed or formatted by accident, right? Fortunately, you have all data on your iPad. Under this situation, you may want to transfer iPad data to iTunes library.
iPod offers three ways to transfer music from your computer. You can select one of the following update modes from the iPod Preferences menu in iTunes:
1. Automatically update all songs and playlists. This is the default mode, in which your entire music library, including playlists, is automatically synched to your iPod. If the music library on your computer exceeds the iPod storage capacity, iTunes will offer to choose a selection of songs to sync to iPod.
2. Automatically update selected playlists. With this option, iTunes automatically copies only the playlists you have selected to iPod when you connect it to the computer. This option can be selected by accessing the Music tab of the iPod settings.
3. Manually manage music. You can also choose to transfer music to iPod manually. This allows you to drag and drop individual songs and playlists from iTunes to iPod. You can find this option by accessing the Summary tab of the iPod settings.
