I have a ton of smart playlists in itunes. Basically every artists I have has their own designated smart playlist with criteria to update automatically if any track is added that they are "guesting" on (lots of hip-hop music). All these smart playlists are also set to live update which is subsequently slowing my system down as I tag new files. Is there a way to update all smart playlists manually? I was looking on doug's applescripts page and coudln't find anything. Anyone have a similar issue as mine? If so, how'd you get around it? I was thinking I could turn off live updating on all non-rap smart playlists since that seems tob e the most "guest" heavy of my music but I'm still exploring my options.
