Easy installation on Debian, hard difficult to configure.But when that is done its easy to use.
Excellent and lightweight player. I keep it open in a tmux window all day long. I love that you can set the key bindings to whatever you want. Combine the ability in this player to execute shell commands with fetching lyrics on the command line (instructions for which you can find using Google), and you have a very versatile player.
I haven't seen a music player like it. It is my main music player. Very well written.
