Well, I've tried it since this comment, and I'm using it occasionally (primarily because I like the Delfin app for Arch Linux), but there's a lot of reasons I still prefer Plex. First and most importantly, I use PlexAMP as my primary music player and I have 1tb+ of music that I don't feel like perfectly setting up again. It's a huge amount of work, and I listen to a lot of lesser known shit that just isn't easy to gather data for, and a lot of Various Artist shit that I'm really particular about how it shows up.

The other big issue I have is that Collections is a separate tab in Movies, rather than being listed alongside the rest of my library like in Plex, and that's really just not useful for me. It automatically populated my collections just fine, but if my primary Movies tab is just gonna list each individual movie and I have to actually go to the Collections tab to see collections, it's just not how I like my library. If I can find a solution for this it'll go a long way to pushing me toward JellyFin.
