I’ve been using Google Play to upload albums which I originally copied from actual physical media. I’ve been playing them from my phone on various cars using Play. I’m currently borrowing one which has Android Auto which provides very limited functionality for Play.
But Play is coming to an end and we have to migrate to Youtube Music. You download the new app and it transfers everything from Play. Open up Android Auto and the new icon appears.
All well and good, then.
Want to use it with Android Auto? There’s a fee for that.
