Creating a Smart Playlist
You can create playlists of certain types of music, songs with certain ratings, or songs that match other rules. iTunes can update these playlists automatically.
For example, you could create a playlist that’s no more than 5 gigabytes (GB) in size and includes your most highly rated jazz songs. Or you could create a playlist of songs by a particular artist. When you import a new CD from that artist, the songs can be added automatically to the Smart Playlist.
To create a Smart Playlist:
Choose FileÂ > New Smart Playlist.
A Smart Playlist icon has a gear on it.
To change a Smart Playlist, select it and choose FileÂ > Edit Smart Playlist.
