Statusnet-Music is a plugin for StatusNet which allows it to serve as a service similar to last.fm, but with all the benefits of open, distributed software. (see the Franklin Street Statement for more on this topic).
Statusnet-Music is a Google Summer of Code 2010 project by Ian McEwen. The development installation of status.net for this project can be found at http://sn-devel.ianmcorvidae.net/.
At one point, Open Hub analyzed source code for this project based on code location(s) available at that time. Since then, the code locations have been removed.
