I find the new Siri “selection” feature for music services to be frustrating. I use Dark Noise at night to sleep or when I’m writing to aid in my concentration. After using Dark Noise, when I get in the car and tell Siri to play “x”, I’m told that she can’t play that in Dark Noise so I have to start prefacing my command with "In Apple Music play “x”. This is a new feature that is a step backward. Just give me a toggle to select my default music player which is always used unless I explicitly ask for something to be played in other service and then reverts back to the default.
For me, that qualifies as a “rant.”
