Title: GNU FM
GNU FM is the music community platform created in 2009 for the GNU Project. It implements the Audioscrobbler protocol, powers libre.fm and supports federation between many Auidoscrobbler servers, including Last.fm.
The main GNU FM instance is libre.fm .
The front page says (among other things):
"Share your listening habits from your phone, computer or tablet, and find similiar artists. All the music on Libre.fm is freely licensed for you to stream, download and remix.
The Libre.fm community is a mixture of music superfans and artists, where artists can share their music for everyone to enjoy.
We believe we represent a good deal for artists: we only promote artists who choose to share their music with the world."

You can report a bug using the issue tracker at https://git.gnu.io/gnu/gnu-fm/issues .
