Not sure if this is possible but is there a way you can implement a way to seperate in settings how many songs to cache on WIFI and another for mobile network, depending on which network you are currently using. Kind of like how you have the "qaulity" seperated by wifi and another "quality" setting for mobile network. Also, can we get a higher number (like up to 100) songs to cache at once verses just the 1,3,5,10,15 there is currently.
