Media folder and functions

I think that I am missing something.
Why would one want to play media from Home Assistant? I think media and the media folder and I think videos and music. Why would I use HA vs some other more sophisticated media player like plex, emby or whatever or am I missing a more fundamental use case for these features?

Bumping this for future looksies as I’m failing to see any benefit this feature currently has, unless it’s possible to set external URL links inside this for say radio stations, playlists or for casting from a Nas?
