One thing I've noticed after upgrading to iOS 6 b4 is that every music streaming app I've tried produces low quality music, even if in the settings of the app you specifically have high quality turned on. Apps I've tried are: Spotify Pandora Slacker Radio Soundcloud Is it possible that Apple may be limiting the quality that music streaming apps can produce in order to push people towards it's Match service and to buy more songs on iTunes? Or maybe Apple is preparing people as it gets ready to launch it's own service? This problem didn't happen on any other betas. I've done reinstalls of all apps, cleared them, even a full restore and set up as a new device. Thoughts? EDIT: After downgrading to iOS 6 b3, all my streaming apps have gone back to high quality music. I'll refrain from updating until b5 or GM.
