Edited: I have consistently been running into the issue where spotify randomly un downloads songs from downloaded playlists. The app says the playlist is downloaded but when I click into it a ton of tracks are faded out and unavailable. I've tried re downloading the tracks but nothing fixes it. It's typically un downloading the tracks I play most. Odd... Exceptionally frustrating especially considering the fact that I have a premium account. My review will remain 2 stars until it is fixed.
