I would like to report a bug. When listening to pandora and using Google maps in Android there is a problem with volume. When Google maps is diving an audible direction it is supposed to lower the music volume until the instruction is finished. This works unless the instruction is at the same time as a switch to a new song. Depending on the exact timing either two things can happen. The most common is for the music volume to remain low even after the direction instruction us over. It goes back to normal when the next instruction happens.
The second possibility is that the new song cuts off the instruction.
I don't know if the bug is in pandora, Google maps or android.
