I do the same but for other purposes.Solitaire001 wrote:One available option is to rename one of the custom fields "Compilation." Then enter "Yes" in the field when appropriate.
I had a similar issue with music tracks. I wanted to be able to separate the music tracks from the non-music tracks. Using the genre field didn't work since some genres, such as comedy, feature both music and non-music tracks. I renamed one of the custom fields "Music" and put "Yes" or "No" in the field. This allows me to create playlists that contain only music.
Then I discovered CustomFieldsTagger
