SubFire Radio, hosted at http://www.subfireplayer.net/radio/ is a playlist generator for the Subsonic music streaming server. It allows one to create 'stations' (implemented as shared playlists with a special JSON syntax in its comment), consisting of lists of generators, each a configuration of methods of the the Subsonic public API.
More information can be found on the help page at the original support site.
The SubFire Player and SubFire Mobile apps are both able to run the station generators on demand for a unique listening experience every time. Stations can be tagged with a category/group in order to be separated by genre or idea on the SubFire players' screens.
It is currently being implemented with JQuery and Materialize.css (0.20).
