Thank you for this brilliant app!
Have already reviewed it on the Play Store & unlocked premium features to support development.
One sincere feature request: Please consider adding an option to d/l tracks offline or some sort of local playback that caches already downloaded tracks. I understand that the tracks are of 10 mins duration. But in scenarios where data usage is restricted, the app becomes unusable for me. With my usage, the app uses up about 100 MB per day. On many days I'm away from a wifi connection so I can't use the app with my 3G connection(which is pricier) due to its excessive data usage. So please give us an option for local playback. Even if as a premium feature, I'll be more than happy to pay up!
