Music apps/services with Roon

It is a little pity that there is not a way to stream music from music apps/services like Stingray Music or Digitally Imported( with Roon. Or services like Spotify Apple Music and Deezer. For example with LMS you can stream with DI.FM. And some others. works with adding urls to my live radio. Stingray Music not. But the best way would be if we could use this services as an extension.
