streams and metadata

I have been playing with emms-streams and with

   (setopt emms-player-mpv-update-metadata t)

it is very capable.

One mild pain point however is that adding a new stream with
'emms-add-streamlist' and friends gives a streamlist with less information
than the built-in streamlists: it lacks the metadata field which is useful
for getting the station name (which can then be fed to a track-description
function to make for a more informative display in the playlist buffer).

Of course, one can populate such a field by hand and this is what I have
been doing but There Must Be A Better Way.  This is the sort of thing that
the unimplemented emms-streams-info.el could be doing but I understand that
querying the url for such information is a bit of a nightmare (does the
stream have ICY tags etc).  There have been previous discussions on this
list about this.

However, there seems to be an alternative: https://www.radio-browser.info
is a free (as in freedom, as far as I can tell) repository of station
information with an API.  Perhaps one could query this to get metadata
about the stream?

One could also imagine other uses of this data like a radio station browser
in EMMS or being able to add streams by name rather than url...

Thoughts?  Worth pursuing?
