The latest beta for Sony’s Music app just added support for Android Auto. Now you can control playback and view album art from the app while in Android Auto, as you can with other apps like Spotify or Google Play Music. Unfortunately, the beta requires being part of a closed community. But, fortunately, we have an APK, if you are interested in trying it out.
There are a few caveats to the beta.
