I'm getting really tired of this **bleep**, honestly. Why the heck do I have a spotify premium account if my offline songs are always automatically being deleted (and I already did the reset on my phone AND my SD card, uninstalling the spotify and cleaning everything left behind from it, losing absolutelly everything hoping that the problem would be solved but STILL. And I know that it is not an issue with my Sd card because I have also offline downloaded music from Google Play Music and I never had a problem with them, ALSO only the Artists songs and Albums are deleted, the playlists that I have downloaded to listen offline are still there.
