If you’re looking for a console based music player and use MPD, ncmpc is a pretty impressive solution.
It lacks some of the functionality offered by Cantata, but it’s about as lean as a music player can possibly get. The software is in active development.
The software is pretty stable although I did experience the odd crash including accessing key configuration.
There’s also ncmpcpp, which is very similar to ncmpc, but adds additional features.
