I'm having this problem where over the course of a couple months songs from albums in my library will stop appearing. (If I click the album, then click "view full album" they exist, so it's just that they've been removed from my library, not from Spotify.) After a while I will have no songs, just a list of albums (some of them, but many are simply gone) with no songs in them. (They can still be accessed through the above method, but ALL of the songs on hundreds of albums are no longer displaying in my library.) I also can't re-add the songs.
Reinstalling Spotify fixes the issue, but I've done this twice on my home computer (Windows), and once on my work computer (Mac). Is there any way to stop this from happening?
