Does Jellyfin allow you to bring in your music libraries?

Also, does Jellyfin have Samsung TV clients, or do you need to cast from your phone? I’ve been trying to de-Google myself and I don’t want to have to keep investing in Chromecasts, and part of the reason why I’ve stuck with Plex is because their app is everywhere.

Are there any current major limitations compared to plex? Remote access ok?

I’m legitimately curious as to what has changed with Jellyfin, with comparing to Emby, that would make this statement true: “that has far surpassed it at this point”
