When I am riding in my car I have my android phone hooked up to the sound system via bluetooth. I download an album to the Spotify app my phone at home on wifi because I am cheap and don't want to pay data costs. When I listen to a downloaded album on repeat, then only the downloaded album plays. However, if I do not have the album set on repeat, then, when the album is over, Spotify starts playing something else. Usually it is something on a different album by the same artist. This incurs data costs, which I would like to avoid. So, is this a bug or a feature? How can I listen to a single album with Spotify and have it stop playing when the album is over when I'm hooked up to bluetooth in my car?
(NB: I haven't tried this outside of my car using cellular data, so I'm not sure if that detail is spurious or important.)
