Only classical music, but I just found this: IDAGIO - https://www.idagio.com/. .It is half the price of Tidal, streams FLAC lossless, and has huge library. I would ditch Tidal in 5 minutes but I am hooked on Roon and Bryston BDP-2 as an endpoint. I would gladly pay $150 a year subscription for even basic integration with IDAGIO.
Roon won’t do basic integration. However you could try contacting Idagio to see if they have any plans to work with Roon.
