@jbm Another reply no longer for Neil, but for others who may find this thread:
The #RoonLabs metadata support is such that artists or engineers in credits, or people or works referred to in text writeups, can hyperlink to those things elsewhere in your library. It's a phenomenal way to explore your music.
If you subscribe to Tidal and/or Qobuz, those streaming libraries are hooked in and feel like your library is just bigger now.
Also: #RoonReady networked audio equipment just works.
