I currently host Navidrome, which has an okay web player. On Android I use “Tempo” (though it is unmaintained) to connect to it, and on Linux I use Tauon (though it has very poor playback). I could not find a native Linux client that is not buggy unfortunately, so I’m also on the lookout for better solutions!
I’m not familiar with the device you are talking about but every client I tried supports MPRIS, which are the regular media controls that can be used via the playerctl
command, so you should be able to hook things up that way.
Yet enforcing your copyright is exclusive to the rich. I had to move off of GitHub because of Microsoft infringing my code licenses and selling them as “GitHub Copilot”, and I have no way of fighting back/recover my losses.
