According to one developer, Spotify is the perfect example of what can happen when an API is poorly managed. Software engineer Stein Magnus Jodal is the developer behind the open-source music server, Mopidy. He has been a Spotify customer and user of its libspotify SDK for years. As Jodal explained in a blog post, libspotify was integrated into a number of open-source projects, including Mopidy, as well as music devices like AV receivers and possibly even cars.
