This is a Logitech Media Server (LMS) (a.k.a Squeezebox server) plugin to browse Spotify playlists from 22tracks. It is not really needed, because a Squeezebox can already browse Spotify playlists. This plugin is there to make browsing those playlists a but easier, and to provide an upgrade path from the old plugin that streamed from 22tracks own web site, to the new implementation with Spotify streams.
To install, use the settings page of Logitech Media server. Go to the Plugins tab, scroll down to Third party source and select 22tracks. Press the Apply button and restart LMS.
The plugin is included as a default third party resource. It is distributed via my personal repository There is no need to add an additional repository, because this is an official third party repository. However, if you want to, you can add the repository directly. A new version might be earlier available in this repository:
http://danielvijge.github.io/squeezebox-22tracks/public.xml
The old version of this plugin is available in the brach old-22tracks. It is kept there because it is a nice example of a plugin that reads data from a JSON feed and plays tracks from a remote source.
