What EXACTLY does 'Kind' mean in Smart Playlists?
Can anyone tell me what terms does 'Kind' require to actually work in a Smart Playlist? I have tried "Song"; "Audio"; "Movie"; and "Show" which all fail (resulting in empty Smart Playlists). I am experiencing the common "iFrustration" that increasingly appears to be designed into the Apple user experience.
A support page containing all the valid variables / terms for use in iTunes Smart Playlists would, I guess, perhaps be deemed by Apple as verging on a manual—and so 'a bad thing'.
