Broadcast using this tool is a livestreaming software for Icecast/Shoutcast that records your virtual soundcard and can apply metadata from dbus. I can't get it compiled on my end so I think some work has to be done so it works on Solus. I use it to stream my own radio show to a webradio and I think a lot of people will enjoy the inclusion of that package.
