I have a Spotify premium account, and I often download whole music albums for offline listening when I'm driving. Recently, after the whole album I've downloaded has finished playing, recommended songs will start automatically playing that I haven't downloaded and are therefore streaming. Before this started happening, my music simply stopped playing and I heard silence, telling me that my album has finished. Now, I might not know that my album has finished and I'm streaming music for a few songs, which is using data. I don't have a lot of data to spare, and I don't want to use it unknowingly on streaming music. I download my music for a reason. How do I get Spotify to stop automatically streaming music without my knowledge?
