We have covered a lot of ground in this chapter; we started by creating an application on Spotify and learning our way around its developer's website. Then, we learned how to implement the two types of authentication flow that Spotify supports: the client credentials flow and the authorization flow.
In this chapter, we also implemented a whole module wrapper with some of the functionality available from Spotify's REST API.
Then, we implemented a simple terminal client where users can search for artists, browse the artist's albums and tracks, and finally play a song in the user's active device, which can be a computer, mobile phone, or even a video game console.
In the next chapter, we are going to create a desktop application that shows the number of votes given through Twitter hashtags.
