Android phones, apps and tablets

I'm just coming to terms with the impact of using Google Music on data usage :-) If my calculations are correct then it will take a little over 7 hours of continuous play to use up 1GB of data....

(That assumes that you are listening to music with a constant bit-rate of 320 kbit/s. I don't know how Google Music adjusts bit-rate for the bandwidth that it actually finds to be available.)

I've set data limits to hopefully prevent any usage costs for now!
