App deleted all my downloaded songs?

I was on my way to work, and I pulled up Spotify to play music. The app was slow from the get-go and wouldn't let me access my 'Artists' page in my 'Library.' I toggled my data on and back off, assuming that my phone was just slow (I'm on Premium, and I have an ASUS Zenfone 2 Lazer). When I went to an artist page, Alina Baraz (I downloaded all of her songs), all but three songs said 'This song is unavailable.' At first, I figured it was because the artist made the songs unavailable, but to my surprise I checked other artists that I had in my library and it was all the same thing, all songs were unavailable save a handful. Out of nowhere, a Spotify notification popped up in my notification bar saying that it's downloading 723 songs (all the songs that are unavailable, I'm assuming), and I have absolutely no idea what's happening.
