We have lots of experience with integrations of music services. We've done it maybe 20 times in the past. They all were dead ends.
The problem is that they don't make money. Not for the services, not for JRiver. Qobuz can't afford to pay JRiver for the work. We can't afford to support it.
We've added other types of streaming recently, including our own Cloudplay. It's not exactly what you want, but it's pretty great if you can give it a try.
