@lambic Turns out Plex just works. Apple would too. But haven't figured out best-fit streaming service that's good at discovering new music for me - which YouTube Music is.
@timbray@lambic if you find a way to scrobble (I assume there's a Plex plugin, but I don't use Plex) then you can use last.fm to get suggestions based on what other people who listen to the kinds of things you listen to, listen to.
@keverets @timbray Plex has last.fm scrobbling, as well as discovery and suggestiona via tidal (to which they offer a discount).
