+Tagging Options
+---------------
+Generic tagging options like --tag, --tag-from-file, --long-tag allows you
+to set arbitrary tags.
+Available tags and their fcc (four char code) for --tag and --tag-from-file

+you can skip first char and just say like --tag="ART:Foo Bar" or
+--tag-from-file=lyr:/path/to/your/lyrics.txt
