Over the weekend, Sonos has completely overhauled the Apple Music section of its application. The interface is now closer to the Apple Music “experience” as we know it in native applications on iOS and Android.
The older version was, shall we say, quite far from Apple’s canon. This is in 2016 that Sonos has integrated Apple’s music streaming service into its app, allowing Apple Music to be streamed to its speakers (you can also go through AirPlay from the native app).
