It’s a music server, like a self-hosted Grooveshark.
It has a subset of the Subsonic API implemented to use with external applications.
At the moment they have a docker installation option:

However, it requires docker-composer (makes it a huge pain to use with Unraid, etc), isn’t as easy to install as it could be, and doesn’t have some of the benefits other LSIO images do.
PS. I couldn’t find any other way to make a container request. I asked around in Discord multiple times but never got an answer, and the “Container Requests” category here seems to be locked, with no information on why it was locked or whether requests are even being accepted or where.
