That is the case. I haven't built anything to share playlists in LNBeats, though I'm sure there's enough there to eventually convert an LNBeats playlist to a RSS feed, but that's not something I'm going to get to anytime soon.
But hey, LNBeats is open source, and Eric wrote the code for playing musicL playlists, so if someone wants to take a stab at it, please do.
