When I first started using the T505, the volume up (to change the song) and play/pause button worked with Pandora. The 3rd time I tried to use the T505 with pandora the buttons stopped working. Then I tried using the T505 with Last.FM and the buttons worked perfectly. I was wondering if anyone else had this problem and if they found a solution....I already tried to uninstall and reinstall pandora but that did nothing.
