Lol ok your comment just made me realize my mistake, and I’d probably never see it and just go back to Plex instead.
So what happened is that when I imported my Plex library to Jellyfin I created a library named “Concerts” and content type I probably intended to click “Shows” but clicked “Music” instead which I’m guessing at this point expects only audio files, thus, never listing my concerts files on Jellyfin :)
That said, I think “Shows” is probably also not the correct content type here, I think they meant more like TV shows, like The Office or Friends etc. Probably the right content type is either Music Videos or just Movies.
Anyway thanks for the help, I wouldn’t have noticed my mistake if it weren’t for your comment.
Lol read and understand it.
