Access music on Mac mini from a TV

I have a Mac mini running 24 hours a day. It is full of music. I also have two smart televisions in the house (a Samsung and a JVC Fire TV). I would like to be able to browse my music library from a TV, using a native TV interface (ie not have to switch to a different input, or use a different remote). How do I do this? PS I do not have an Apple Music subscription, and I don't really want to pay to access music I already own.
