That feels like a balance but if you want your Spotify playlists synced you’ll also need to pay out for TuneMyMusic, Soundiiz or FreeYourMusic account.
There’s a 15% Soundiz discount code for Roon users on this page.
Although short of full Spotify integration — which is unlikely to ever happen due to Roon’s architecture / business model not alining with Spotify’s — it would be great too see Roon incorporate some of the more basic playlist sync features (offered by Soundiz etc.) directly into Roon, rather than having to pay out for another subscription with a 3rd party.
There seems to be a whole area around playlists that could do with a revamp in a future Roon release. Not only the management of them in Roon, but also the import, sharing and syncing of them with other platforms. The logical first step would be the sharing back of Roon playlists to Qobuz/Tidal. But after that Spotify would seem like the next likely candidate to look at syncing playlist with esp. given it’s ubiquitous usage and strong ecosystem of playlists.
