All of the playlists selected for updating no longer

If I just mclick on some playlists, the rest of my music that I checked in the library doesn't make it onto the ipod. It won't let me select some playlists AND additional songs, but not all.

If you were manually managing music before clicking the Sync Music option, a message appears asking whether you are sure that you now want to sync music, stating that all content already on your i Pod will be replaced.Just moving the file and then reimporting it did the trick though.i Tunes keeps track of your content and playlist in a library file.Click the Sync Music button to go ahead (or Cancel if you changed your mind), which returns you to the Music sync options page.After clicking the Selected Playlists, Artists, Albums, and Genres option, you can then select each playlist from the Playlists list, each artist from the Artists list, and (if you scroll the Music sync options page) each genre from the Genres list and each album from the Albums list.
