If you're interested in #DolbyAudio upgrades of your favorite music(whether #Atmos or any of its other multichannel formats) these are probably two useful resources to track what’s available and/or what gets added:

With the addition of #HDMI #passthrough in #macOS15 I’m finding renewed use for my surround receiver that started gathering dust in recent years. A sample recent submission was RTJ3: https://music.apple.com/us/album/run-the-jewels-3/1598920855 A classic that got an Atmos upgrade a few years ago (yes audiophiles, you can choose your preferred mix) is Kind of Blue: https://music.apple.com/us/album/kind-of-blue/268443092
Anyway it's interesting to compare traditional stereo and surround mixes. What other surround mixes are worth checking out?
