geez, now the audio keeps stopping on Pandora with the screen asleep...but not right away..just randomly. I remember having this issue months ago, but not recently. hope this doesn't mean a reset is in order. grrr.
Pandora is working on a whole new redesigned interface and with holo design. It should be out in the coming weeks. Of course iOS got their version of the update first..
Anyways, I would try a Pandora reinstall first.
