Create a SmartlistSmartlists
Smartlists are Playlists too, but instead of being a list of files, they are a list of rules. You can create a Smartlist that basically says: Play everything in my "Top 40 hits of 1989" Playlist EXCEPT for the Christmas songs and the songs by Aretha Franklin. Whenever you select to play a Smartlist, it will apply the relevant rule to your entire database, including any new songs you may have added to your library that meet the criteria of its rules. So Smartlists are unlike Playlists in that the content or order of songs cannot be preserved—it is not a static Playlist.
