Thumbs up on the Denon 760H purchase. I‘ve got one too. I think it’s the best mid-range choice for the enthusiast. Enough features and power to drive a home theater for the normal person and affordable enough to be a casual living room AVR for the enthusiast.
FYI: AppleTV streaming service app and Apple Music streaming app are both on most every streaming appliance and smart tv now.
I use Music in my 2019 LG TV all the time.
Apple’s degenerate naming confuses this, but lack of app is no longer a reason to not subscribe and watch For All Mankind...
