I had made all my playlists available offline which invovled using alot of data. If you live in rural New Zealand you will know that we don't get unlimited and pay through the teeth for our broadband. I changed my facebook password and when I logged back onto Spotify the next time I had lost all my playlists offline. I had to redownload all on both my deivces which used up half my monthly allowance of broadband. Not happy with this Spotify as I should be able to change my facebook password regulary.
