Searching for a 'library manager' that looks awesome.

As the title says. I have been searching for something like Kodi but more focused on an offline library manager for all the media I have. I can just navigate with the file explorer through my folders but it just looks not that pretty. Is there anything like a library manager to display my videos/music in a similar way of big online platforms? Since I have a lot of things to watch on my drive I don’t actually use much internet lately and I’m searching for something like a good looking UI, but probably I’m not very good at searching :(

Do you know a anything like that?
