Feedback on a great audio server software

Regarding point 2, according to this thread it is no longer possible (from iTunes 12) to set the Description field ("desc" atom) for music files, only video files. As far as I have been able to discover, the use of the "desc" atom as a mapping for Subtitle is specific to Mp3tag and is not a standard mapping that is used by any other tagging program.
