It has been discussed many times in many threads fro a long time. Roon is fully aware of the benefits of adding other streaming services and has been trying to get more all along Indeed long time ago this topic drew one of the few responses on here from thier CEO. If they have gone this far with Pandora I’m pretty sure they will have done the same with the other streaming services and I’m sure they keep on doing this. The sticking point seems to be the deep integration that Roon requires which is not support d by the standard APIs other services have or previous exclusivity agreements that get in the way.
