Spotify-API

This hack no longer works - it looks like there have been some major updates to the protocol since Spotify v4.x, and the jotify project has been discontinued.

In the meantime Spotify have announced an official playlist api at the music hack day in Amsterdam, however there haven't been any updates in a while so I'm not too hopeful this will actually happen.

I got tired of waiting for Spotify to release their API (if they release it), so decided to roll my own based on the awesome work done by #hack.se (despotify) and Felix Bruns who created a Java port of despotify called jotify. Add JRuby, Sinatra and some glue to the mix and you (almost) have an API.

Important: in order to use this API you'll need a premium spotify account! This API is as unofficial as it gets and NOT supported by Spotify in any way.

At the moment the following features are implemented:

• searching [GET /(albums|tracks|artists)?name=Foo]
• list user's playlists [GET /playlists]
• get shared playlist [GET /playlist/id]
• create new playlist [POST /playlists]
• update playlists [PUT /playlists/id]

Prerequisites: Java 6+, JRuby 1.3.x.

$ jruby -S gem install spotify-api --source http://gemcutter.org
$ jruby -S spotify-api-server --account login:password

    ]
  },
  "status": "OK"
}

Make sure that your spotify credentials are working, install warbler and run it in the spotify-api directory, the resulting spotify-api.war should be deployable in any servlet container.

See examples directory for usage. The demo application (lastfm2spotify_loved_tracks) will grab all recently loved tracks by your last.fm friends to create a new spotify playlist. A nice way to listen to some good new music (if you share a similar music taste with most of your friends :)).

Test your changes with rake spec for unit tests, rake integration for integration tests. The jotify jar file is build from github.com/jberkel/jotify/tree/spotify-api.
