So, way, WAY back in 2011~ish playlists did not have dates by which you could sort, so when you added them to a playlist there would simply be nothing there. Then around march 2012 Spotify added dates, and every song you added AFTER that had a date associated with when you added that song to a specific playlist. Every song you had in playlists before that did not have any dates still.
Now all of those songs are gone. Vanished. Kaput.
So, here I'm sitting, looking at my playlists with SEVERAL HUNDRED SONGS gone. Most of it is intact, thankfully; but there are now huge gaps in my playlists. The fsck is up with this? Whose bright idea was it to nuke peoples' playlists without making backups?
How can I get my songs back?
