When creating smart playlist it is possible to include tracks based on different criteria, but it seems not possible to exclude based on specific criteria ! Or am I wrong?
In Apple Music or Audirvana, it is possible, and it is a great way to find out which files were given a rating or not.
One can make a playlist from the tracks that were not rated by excluding the rated tracks.
It is also interesting in making limited playlist if one can define that numbers already present in other playlist should be excluded from the new playlist.
Also, how can I find tracks that have no tag (I suppose it is the same problem of not having the possibility to exclude.
