-      This document shell give a short guideline for recommended tags
-      for use in MPD's Sticker Database.
-      MPD's Sticker Database is a subsystem that enables users to add
-      custom tags. MPD does not alter the media files.

-    <title>Guideline for recommended tags</title>
-    <para>
-      Since there is no standard for tags in media files, this
-      document is trying to give you some help deciding what tags to
-      use.  The selection of these tags tries to cover the most
-      widely used tags.  This way the tags might still work in other
-      players, if you sync the database with your original media
-      files.
-      Keep in mind that we stick with lower case tags with underscores
-      instead of spaces. If there will be a Sync tool in future
-      its easy to change this on the fly, if needed.

-          <para>
-            This tag is used to keep the Genre tag clean, by now
-            having 1000's of genres.  Instead you define a Main Genre
-            for each file and can make a more specific
-            description. This should be one Keyword like "Post Punk"
-            or "Progressive Death Metal" An Alternative name for this
-            tag is "Subgenre", time will tell which one gets more
-            support.

-            This tag enables a last.fm alike aproach which will still
-            work when being offline Keep in mind, that this tag is
-            absolutely non-standard! I am not aware of any other
-            player that uses a comparable tag.
