Figured out I have to set media servers before I can do that. Might want to make the error have a link to be able to do that.
Also, when uploading music, it doesn't seem to be available on lnbeats or am I missing something.

lnbeats is a Podcast client, Nostria has some limited Pocast functionality as well, but no default RSS feeds listed yet. You can paste any RSS feed into the search input and import it to your media queue.
