The Apple Music beta for Android has gained some new features, including support for Sonos and playlist folders that are created in iTunes. Apple Music is set to make its way to Sonos in beta form on December 15, so this likely lays the groundwork for that compatibility. With the added iTunes support, you'll be able to manage your playlist folders from your computer, and have them sync to your phone.
This release also includes some stability and performance improvements, which are always welcome. You can grab the latest Apple Music beta from Google Play now.
