Motorola Moto G 4G — Auto downloading

Dear all
Recently I bought a new moto g4 mobile.
Still I am not fully conversant with it.
Previously I was using Samsung galaxy.
There is one music streaming app called
Subsonic (sangeethapriya.org). I used to listen music in Samsung mobile and the music is automatically downloaded. In moto g4 though I can listen music it is downloaded.
I need your help to solving this problem.
Thanks
