Recover offline playlists from SD card

[Isaacharper]

Yesterday I tried to get onto my spotify account offline, but for some reason it had logged me out. Later in the day when I finally had WiFi I logged in, but the app told me that I had used spotify on too many devices so removed all my offline playlists (I only have spotify on 2 devices). I am wondering if it is possible to restore these playlists to offline playlists without having to actually redownload them as all the data still looks to be on my SD card?
