a)one my major complaints was that the app never recovers from spotty connection. When network goes down music goes down which is expected ( kind of , why doesnt the app buffer music?) but when network comes back music never comes back. b) Non existent buffering: Please take a leaf from pandora's book and look at how fast their music streams under spotty(any) connection. I kept thinking 'hey they are new, they'll figure it out soon', but nothing after 2 years. c) App keeps crashing: i've had several incidents where app crashes and never recovers so i have to completely uninstall and reinstall the app ( and re download al the offline music). unacceptable. The app i have now on my phone crashes every time when it comes up( which was kind of the final straw)
