I would like to get the following feature implemented.
Within the Spotify App a ‘Smart Offline Switch’ would be preferred that is turning Offline mode ON when using 3G/4G and Offline mode OFF when the smartphone/tablet is on WiFi.
From a commercial perspective this would increase the usage of Spotify because in mobile environments you would not hesitate to use Spotify. Also from an environmental perspective we should take care on the explosion of data and provide smart solutions for this. For users with limited data plans or in environments with less mobile connectivity this would support them to use the App.
