For the past few months I’ve been a-b-c testing YT Premium, Spotify and Apple Music. AM is by far the worst. No other service stops playing downloaded music and forces me to connect to WiFi to continue playing music. On a hike, that is just awful to experience. AMs spatial audio is terrible via headphones as well. YT musics audio quality is on par with AM but the UI is bad. Only real reason to go with YT is if you watch a lot of YT, in which case you’ll have no ads. I’d personally go with YT over AM since Apples apps are bad. In the end I went with Spotify. Better apps, available on more devices, and their audio streams sound better than the other two.
