radio: allow export/import using xspf (or opml or m3u os pls) format?

probably https://xspf.org if anything?

opml, the outline format, I’ve seen used by a few apps that allow nesting

Radiodroid uses m3u export/import

some related steam playlist content here

I’ve not really dived into netradio and MPD yet because the cost of using it instead of my existing radio app has been too high, but, going forward, I’d like to be working things through MPD, someday, maybe

As an MPD client, MAFA is focused on controlling MPD by using the MPD protocol.

You can add your playlists to the playlists directory of MPD and then use them from MAFA.
