IN APP SUBSCRIPTONS AND AUDIO PLAYER without download issue on Android

Simply.
First .
The audio player allows to download the music , I ask an option to avoid this which makes a serious audio app useless to be built like now.
Even better plus more graphical customization .

Secondly , an in app recurring payment method.

A real audio app must allow to sell music and plan .

Please vote or they will think this features are not important to be developed.
Thanks
