I have spotify running on my (Linux) Desktop. I am using a prepaid (pay per MB or hour) internet connection and thus don't have the luxury of being online all the time. So I downloaded quite a few playlists for offline listening. My Desktop unfortunately just told me offline access has been revoked. I read the thread on why that can happen and how I can re-enable offline availability, but for some reason, spotify deletes all offline files first, and then starts re-downloading them. THis is pretty annoyinng on my internet connection. I have, fortunately, a backup of all offline storge of spotify (form the Storage folder), and copied the backup back to the Storage folder. This used to work fine, and instead of redownloading files, spotify would just mark the songs as being available again. Now though, as soon as I start spotify, it deletes all these files again, and starts re-downloading them.
Is there any way to resolve this so spotify uses the files that I already downloaded instead of redownloading them? If not, it will take me multiple days and a lot of money in internet connection to re-download all files again, and this being the umpteenth time this happend (normally only on my android devices, lately with the change from spotify to the spotify-music app), it kind of makes me exasperated with spotify and is making me consider saving the €10 per month I am paying now, and falling back on illegal downloads as I am on the move a lot, and travelling to many different countries with bad internet connections. It will be both cheaper, and more reliable.
