According to Beta Labs,
We are happy to share release 1.6 of Soundtracker Radio for S60 5th edition and Symbian devices. In addition to further improving the musical experience and fixing a number of issues signaled to us but the Nokia Beta Labs community it also brings the Symbian Anna and Symbian Belle devices to the list of compatible devices.
We recommend to install Java Runtime 2.1 beta for S60 5th edition devices before installing Soundtracker. We also recommend to remove any previous build of Soundtracker and install this new build.
There is no changelog at the moment. The app can be downloaded at http://betalabs.nokia.com/apps/soundtracker.
Do let us know what you feel about the app…!!
