I don't think I'd go as far as soul suckingly bad, but I did detect a difference. As a streaming option with a pretty good library it definitely sounds better than their basic and comes close to cd. I probably won't keep it when time comes to start paying for it but I was pleasantly surprised and the library is pretty extensive for my tastes in music.\n\nWell I think I may have found the issue. I had originally installed the app from the Microsoft store. After doing some searching on this issue. I uninstalled the app, then reinstalled it directly from Amazon. I don't why this would or should make a difference, but it definitely did. \nHowever whether or not I prefer this over spotify premium is yet to be determined. Comparing identical tracks one versus the other, I do like the vocals better coming from spotify. But I do like the older tracks on amazon hd, seems to give more spaciousness. So I am now more pleased with the amazon hd than I was originally.
