Emacs can be a mobile music client…
I was screwing around with playlists on my desktop and had meant to see how well things work on my phone… Turns out it works pretty well.
I’m going to assume that if you’re reading this, you probably already know how to install Termux on your phone, and from there install emacs.
Once you’ve got that out of the way, install mpv and either (or both) exiftools or mediainfo. All of which should be installable with pkg install whatever. I was kind of surprised to find mpv available, and it of course doesn’t play video, but it does audio pretty well.
