Made tags of flac files using Mp3tag. Noticed that the tags do not appear in Properties (Properties\>details\>tags). Ran the files through mp3val which generated the error ' **Unknown file format**.'
Here is a copy of the metadata.

MP3val evaluates only mp3s, no flacs.
For the tag-display-problem see this thread:

There seems to be a length problem for tag fields. And classical music has very often such long titles.
