As far as I know The GNU FM project is not longer available. Mostly of the sites that used its software, with the exception of libre.fm, are down. The software is outdated, the last commit in the git repo (mirror) was made 7 years ago. Their catalog is small, and also outdated.
As a community it is different; many sites that are not related to the original project still refer to themselves as librefm, are in many languages and carry the essence of publishing CC/libre content.
