Yeah, I've had this problem before, But I'm quick to blame Spotify's UI because it sucks, when a new album releases, I do not care and the last thing I want to see when I'm driving is a pop up for it. (Yes, this has happened to me), I have a single playlist that I play all the time and if a song that's playing that I don't like or don't feel in the mood for I skip it, using the physical buttons on my steering wheel, and not taking my eyes off the road, (not that Spotify's Shuffle algorithm is any good, it's absolute dog shit).
And before I leave, I always make sure it's set to that playlist as I switch to alternative playlists when I'm doing other tasks, and it's incredibly difficult to try and change playlists while driving, I learned my lesson a long time ago and I just pull over or mute the stereo entirely and sit in silence. (No, I've never had an accident before, but I don't need to, to know that trying to navigate a touch screen while driving is a bad idea, even at very low speeds).
For some stupid reason as well the user interface is different per phone device, my partner hates it on a new whatever the fuck Samsung's new flip phone is, because the seek bar is a wobbly groove for some stupid reason, and the album art is in the wrong spot and for some stupid reason they keep insisting on changing the interface because product managers have to justify their job....
I usually have it where if I'm driving with my partner, I get her to set the playlist, but she always puts her trash music on.
Google for some stupid reason also decided to give me Gemini so trying to set navigation through voice commands is an impossible task until I changed it back, it's still not perfect but it's better than arguing with a clanker.
