Nice update. However, it appears that you have implemented background audio not completely right. When the app is streaming background audio, and you double click the home button and scroll left to the audio control panel, your app icon is not shown (instead the previous audio app is shown) and you cannot stop the app playing sound with the controls. You can only stop the sound by opening another sound app, such as the ipod app, so that it takes over the background sound api, and then stop it.
