The Windows Mobile App just blows in sound quality. I use Pandora when booted into Andorid and for a little while when I selected high quality in Android and switched back to WinMo the High Quality Audio seemed to be coming through. But now it is back to the 48kbps and is worth than static FM through my SE535....STRUGGLE

(Prefer how Pandora will keep playing where-as Slacker gets hung on the commercials- while riding I don't always have time to switch stations but atleast the audio quality is bearable)
