The android app doesn't function properly. The lockscreen widget doesn't appear most of the time. Navigation can't mute it to read directions over Bluetooth. Steering wheel controls don't work most of the time. I have to go in and close all my apps to get this thing to work properly, which is annoying when I'm running errands around town and I just want things to work. This is one of the worst music apps for a smartphone. The service is great! The app sucks.
