Missing tags should not use "Unknown"
Submitted by Alex Lancaster
Link to original bug (#328971)
Description
Missing tags should just be listed as blank or somehow marked using a non-standard font or colour, rather than "Unknown" to avoid confusion if there really are albums/titles/artists that are called "Unknown".
This will be useful for addressing bug #157340, and other situations where you might want ignore tags that are blank. If this was implemented, there will also need to be options for every option menu that searches on a tag in auto playlists to select tags that are blank specially rather than search for "Unknown".
For example, you could have:
Artist [contains]
[does not contain]
[equals]
[is blank]
If the last last option was selected it would grey-out the box.
