Apps like Soundcloud will lower the volume when a notification or GPS voice direction is played (known as ducking). Spotify still pauses the track. This is much more distracting, particularly when driving.
A separate volume control for the Android app would be a great addition to an already impressive application. This is needed for those of us that use Google Navigation, Google no longer separates the audio for navigation from the main audio feed and the new voice of navigation is very soft. When listening in the car the volume of the music has to be turned up fairly loud to be able to hear the navigation audio. If you have others in your car you really cannot use Spotify and still be able to carry on a conversation. Separate audio controls for the Spotify app should solve this quite nicely.
Ever since the new update, i'm are not capable of searching for songs/artist/albums on my Android device if I am offline. This is incredibly frustrating because this means I have to scroll through me playlist (containing over 700 songs on each playlist) to find one indivisual track,arist, or album. Spotify needs to bring this feature back to android devices.
