I hate to tell you, but Siri and other voice assistance are not good at controlling music playback. I have been waiting for that specific feature to get “good” for over a decade now.
The closest one came to handling controlling music playback well in anyway was Cortana but even Cortana didn’t do the things that I needed to do with my voice while controlling music play.
The biggest Used case for me was always hey Cortana hey Siri add a specific song to now playing and play it next. No matter what on any operating system. The voice assistant delete the entire queue and then probably plays the wrong song. Not only will they play the wrong song, but they will play the entire album from the wrong song if it is available so now I’ve gone from a playlist that I was building and listening to on loop for potentially days to some album that I don’t wanna listen to because it could not just add a song next.
