Agreed, if you’re a single-app user then something like Spotify works just as well, as long as they do a great job of maintaining to-the-second sync across devices. Audible does a good of that as well.

That just puts you in the space of needing all apps to be available on all devices.

Does the car support different Spotify accounts on each driver profile? If not then you can say goodbye to personal playlists and favorites and podcast progress…

That way also makes it mandatory that you pay for the redundant car data plan that most people wouldn’t need but which they so badly want you to buy for another $30-40 a month.
