I'm an Emacs graybeard, so complex keybindings don't scare me. My problem with ncmpcpp is twofold:
It relies on MPD which is always a PITA to properly configure. Pulseaudio always managed to make it not work on a fresh system. Hopefully with Pipewire it'll be better.
The config format make no sense whatsoever. Especially the one with keybindings. It's so cryptic I just stopped trying to understand it. Again, I'm an Emacs graybeard, to stress it as a point of reference.
