Sony Mobile has updated the beta version of the Music application moving it to build number 9.0.5.A.1.0beta. This update includes everything from the stable release (9.0.5.A.0.0), including Quick play, but it also includes an option to now hide folders within the ‘Folder’ view. If you want to bring these folders back, you will notice an option at the bottom of the Settings menu to “Show all folders”. The update is available to those in the Music Beta or you can download the APK below.
