This is a little demo app that shows how to call the Echo Nest API from within a Spotify App. To run this app create a subdirectory called 'playlister' in your Spotify directory (on a Mac its ~/Spotify/playlister). and copy the project files into that directory.
Load the app by typing:
in the search bar. The app will create a list of tracks for the given seed artist. Press the button to generate another playlist.
You should use your own Echo Nest API key. Replace the demo key (N6E4NIOVYMTHNDM8J) with your own key to get full API access.
