Spotify app deleting downloaded songs

[silasssales]

Over the past few days, the spotify app has repeately deleted most(about 90-95%) of my downloaded songs, this means that I have to redownload everything, which is alot in my case, and if i dont realize that it has happened at home or work, than I dont have any music to listen to on my commute. 

I literally open up the app and sometimes the songs are there, sometime they are not and the size spotify takes up on my phone shows that the songs are deleted, not just hidden. 

Specs/other info:

LG G4 

Listen aswell on two computers at home, and one at work (not concurrently).
