It's obviously just a boolean customize-setting, defined as

  (defcustom emms-player-mpv-update-metadata nil
    "Update track info (artist, album, name, etc) from mpv events, when it is 
played.
  This allows to dynamically update stream info from ICY tags, for example.
  Uses `emms-player-mpv-event-connect-hook' and 
`emms-player-mpv-event-functions' hooks."
    :type 'boolean
    ...

Which is supposed to be customizable interactively via the usual
"customize" or "customize-group emms-player-mpv" interactive commands.

I set it via:
  (custom-set-variables '(emms-player-mpv-update-metadata t t))

And it should obey all the usual rules wrt customizable vars in emacs.


But trying interactive customize just now myself, found that
"emms-player-mpv" group might be missing (defgroup ...) definition
and signals error on rendering its two values with :set handler.

Not sure why latter happens - pretty sure it used to work, 
will need to look into it a bit later.
Might be related to lexical binding change or changes in emacs.
