Peter c'mon that doesn't answer this annoying question of how do songs become unplayable offline when they were playable offline earlier that day?
It's like Spotify keeps re-syncing or re-downloading for no reason. OK so there is enough space, everything is working just fine. The complaint is with the Spotify App Peter and how it was programmed to operate. This is not a problem of user error. There is no reason if I'm paying my premium that Spotify can just randomly tell me all of my songs are unavailable for no reason that I am responsible for. Are they playable offline or not??? This is an annoying core feature of Spotify. Can you at least tell me why this is not clearly explained when you are encouraging the user to purchase premium in the beginning?
Example: I turn my phone on and fire up Spotify and songs are unplayable when they were just 4 hours ago. I turn on the internet, songs start becoming available randomly. Internet goes out, no more songs are available, only the ones that downloaded while internet was available are playable. I have plenty space, all the songs were playable 4 hours earlier and still would be now if I could connect to the internet. So how is this possible? It seems clear to me that premium user or not, you are tethered to the internet if you wanna use Spotify?
