After the last update on my Android, Spotify changed so that when an album ends, the album radio automatically begins instead of just going to silence. Tbh no idea how most people feel about this, but I usually listen to music by the album - it's important to me that the album ends as the artist intended. I don't want to it to just flow into other music. Especially since I don't really use the album radio feature to begin with.
If this is something people want, there should at least be an option to turn it off. This is irritating enough I'd leave Spotify because of it.
