Works really great. I use it a lot and the interface is easy to navigate.

Why not. Peer to peer sounds like a good idea: https://radicle.xyz/

I love the colour!

Hey, nice rice! Is this polybar?

I dont know about this. I like seperation of services. Navidrome is for streaming and anything related to finding out what i want to hear is handeld by my client (Symfonium) or by last.fm or listenbrainz. Plex is still probably the best self hosted music solution, if you dont care about privacy and pricing. But i do, so it is no option for me. I also never really used tools to explore my music libary. Im more of a Album listener, so i dont really use Playlists or somethin like that, so just looking through random albums in my library is often enough exploring for me :)
