polspot

Polspot is basically the same as the above despotify client, only it’s using the Spotify client library API.

Features:

• Searching
• Playback of tracks found in a search
• Playlists are not supported
• Works with either libspotify or libopenspotify
• Platforms: Linux, Mac OS X (Mac OS X requires libopenspotify)
• Author: Daniel Stien
• URL: http://github.com/dstien/polspot

jotify

Jotify is a clone of the official Spotify client, written in pure Java.

Features:

• Familiar GUI
• Playlists
• Track queueing
• Searching
• Cross-platform
• Platform: Java 1.6
• Author: Felix Bruns
• URL: http://jotify.felixbruns.de/

qtify

Qtify is a GUI client that’s written in Qt (C++) that was primarily written to bring Spotify to the Nokia N900 platform (Maemo). It also works on Linux, and with Qt being a crossplatform development framework, adding support for other OSes such as Mac OS X or Windows merely requires the audio part to be ported.

Features

• Playlists
• Searching for tracks, artists and albums
• Playback (play, pause, resume)
• Qt 4.6 based minimalistic GUI
• Uses libspotify
• Platforms: Linux
• Author: Robin Nilsson
• URL: https://garage.maemo.org/projects/qtify/

Third party Spotify client libraries

On April 7th, 2009 Spotify released libspotify, a client library that can be used to build applications around Spotify’s music streaming platform. Initially only 32-bit Linux was supported but as of January 15th, 2010 it also sports support for Linux on 64-bit platforms. Hopefully we’ll see support for even more platforms in the future.

libspotify is a closed source library  and probably needs to stay that way. Reasons for this likely include both a requirement on their part to protect the raw audio feed aswell as preventing abuse of the system that keeps track of what songs have been played so artists can get paid properly.

Since the release of despotify three different open source client libraries have been created. Their main benefits include not being dependant on what hardware platforms Spotify can actively support aswell as having permissive software licenses.

NOTE: Just as with libspotify, you need a premium subscription to be able to talk to Spotify’s platform with third party client libraries.

libdespotify-simple

Written mainly by Björn Stenberg this is a simple-to-use library for accessing Spotify. The library is synchronous in its operations and hides the complexity behind Spotify’s multiplexing protocol.

Features:

• Playlist retrieving
• Playlist modifications (renaming, controlling collaboration flag)
• Searching
• Cover art
• Audio playback
• Simple to use
• Language: C
• Platforms: Linux, FreeBSD, Mac OS X, Solaris
• Author: Björn Stenberg and others
• URL: http://despotify.se/source-code/

jotify

Written from scratch in pure Java, Jotify is often first to support new features found in Spotify.

Features:

• Supports most operations that libspotify does
• Language: Java
• Platforms: JRE 1.6
• Author: Felix Bruns
• URL: http://github.com/fxb/jotify

libopenspotify

libopenspotify aims to be a API compatible, cross-platform drop-in replacement for libspotify, free of licesing issues with its permissive 2-clause BSD license.

Features:

• Most things libspotify supports except playlist modification
• API compatible with libspotify 0.0.3
• Permissive 2-clause BSD license
• Language: C
• Platforms: Linux, Mac OS X, Windows
• Author: Noah Williamsson
• URL: http://github.com/noahwilliamsson/openspotify

Bindings for Spotify client libraries

Jørgen P. Tjernø has written spytify, Python bindings for libdespotify-simple.

Jesper Särnesjö has written greenstripes, MIT-licensed Ruby bindings for libspotify.

GitHub user jptix started writing Rubi-FFI bindings for libspotify with spotifyrb.

Doug Winter has written pyspotify, Python bindings for libspotify.

Jonas Larsson has written libspotify-sharp, C# bindings for libspotify.

During Music Hack Day in Stockholm, Rasmus Andersson started spotifycocoa, a project to bring Cocoa style bindings for libspotify.

GitHub user romnes has written libqspotify, Qt bindings for libspotify.

The source code is available on GitHub and there’s an introductionary video of it on YouTube.

despotify is about providing an open source client to Spotify’s service and providing tools to allow third parties to develop new and cool services that make use of Spotify’s platform and services.
