I typically use Tidal, but any of the streaming services work with BlueOS. What I did add and absolutely love it is Roon. Roon automatically reads the music files on my computer, categorizes them, etc. So, through the Roon app on my, say, iPad, I can play Tidal or remotely stream anything that is on my computer or attached hard drive. Theoretically, you can do this through the BlueOS, but it was a little convoluted and above my computer literacy. Or maybe I'm just lazy...
