I last posted on this topic quite some time ago, and I am sad to see little if any progress in integrating Amazon Music HD into Roon. I’ve seen the replies that state it is Amazon’s problem - they must do something to permit this to happen. Perhaps someone with some knowledge on this can say what it is that Amazon must do and whether anyone has asked them to do it. Does Amazon ask for money to do whatever it is they must do? (They shouldn’t, because there must be more Roon users than just me who would purchase their service if it became available on Roon.)
