Yeah, the entire user experience for radio has been redesigned from scratch. It’s nothing like what is there now.
Yes to your two points–stations from the directory will be automatically updated as new streams appear (or are retired). Yes, the plan includes reliability testing–which will incorporate both feedback from successful/failed plays within Roon as well as some kind of more explicit testing from our servers.
The stations will be drawn from a few sources, including stations that have been entered into the current radio interface (obviously this requires a bit of data mining/cleaning/grooming/deduping/etc to make it nice).
We’re going to make a moderation interface (website, outside of app) available too, so people from the community (including end users, partner companies, dealers, etc–remember lots of languages + regions of radio to cover, and plenty of interested stakeholders tied to those markets) can help keep things clean and organized and complete–very much like the system we built for creating/maintaining translations of the Roon interface.
