So i have spotify premium, and i already sync the songs of my preferences that are on spotify.
The catch is that the songs that i have on my pc (and that spotify already tracked on) cannot be sync to be heard offline on my android device ( Moto g ), they appear on the playlist, but are not available to be heard.
Is it possible that i can listen to them via offline mode on spotify? and if it can, how can i do it?
Thanks in advance
