How do you up date the library in itunes? Im always removing and adding music and it needs updateing all the time. Other that totally clearing it and rescanning takes ages!
In i-Tunes, choose "Edit " from the menus at the top. Then choose "Preferences" from the drop down menu. A box will appear.. Click the 'iPod' tab and make sure that the "Automatically Update all songs and playlists" option is selected.
