How use the tabs "album-tags" and "interpreten-tags"

Issue description:

It is a question how to use album-tags (interpreten-tags). I use mp3tag (Windows) to create/modify the tags of my files. I created an custom tag (Album_Best) und alternative an (in the list of mp3tag an existing tag “ALBUMSORT”. Than i copied the album to my phone, started in Symfonium the synchronization of my local device. After synchronization i selected the tab library and there i typed on “Album-Tags”. Symfonium showed that no media can be found. When i type the search icon und type the album tag (Album_Best; alt. ALBUMSORT), nothing can be found too.

What i have to do to use this feature (what kind of names for the tag i have to use)?

I had read this, but i wasn’t able to understand it completly. What i have to do now concretly? I use Symfonium at the Smartphone and the app “Mp3Tag” (last version) at my windows pc.

Please give me an example, how i have to add a right tag so that Symfonium can evaluate this. I had added “AlbumSort” without success for Symfonium. Should i use “Album Sort” (?) or it is necessary to install other software?

OK, i added the tag “TAGS” (with “Album1”) and so Symfonium found it.
