A free program for Android, by Sony Corporation.

The Sony Auto Play app is a music-centric audio-manager app. It allows you to stream music to your speakers, headphones, or any connected device from a number of Sony-partner services, including Spotify, Deezer, Google Play Music, and more. You can also add audio-only services like Pandora, iHeartRadio, Google Podcasts, TuneIn, YouTube Music, and more to the mix.

How does it work?

When you connect to a Sony service, the app will automatically check for updates and download any new ones. When you put on your headphones, the app can read out the audio level and mute your device's volume if it's too loud.
