Transferring specific playlists to iPod

You can set iTunes to update iPod with selected playlists automatically when you connect iPod. iTunes erases songs from iPod that aren't in the selected playlists.

To set iTunes to update iPod with selected playlists, connect iPod to your computer and open iTunes. Select iPod in the iTunes source list. Then click the Options button and select "Automatically update selected playlists only." To transfer playlists manually, click the Options button and select "Manually manage songs and playlists." Now you can drag individual playlists from iTunes to iPod to transfer them.

Transferring playlists is useful if you only want to update iPod with a portion of your iTunes music library. You can also set iTunes to update iPod automatically with selected songs only.
