Apple Music with Dolby Atmos is very good, Besides the Apple gear, HomePod's, and their over priced head and earphones an AVR can decode audio Dolby Atmos. I like Apple Music but I have SoundCloud and BandCamp as alternatives. Band camp does not cost anything to load and you can listen to music there at the MP3 level, but you can purchase music directly from the artist. Once you purchase album it is yours in their cloud, and you can download a copy at anytime, MP3, FLAC, ALAC. In addition you can purchase CD, LP, and even cassette tapes in some cases. A purchase of a hard copy includes the album in your cloud account. downloadable as mentioned above. Supporting a musician directly feels real good. With SoundCloud you can use it for free but a paid subscription allows you to download, and have HiRez playback. SoundCloud has a unique catalog of music.
