cmus won points with me years ago when it was able to play back ogg files of moderate bitrate without skipping a beat (pun intended) on old hardware — very old hardware.
For me, that’s still its strongest point. It’s an exceptionally lightweight application (due in fact, I believe, because it is written in C) that is at the same time wonderfully complex.
All the same, I admit openly that I dislike music players that keep databases or manage my music. As I said a long time ago, I manage the music. The player plays it.
So I respect and revere cmus as an excellent example of lightweight and ornate software.
But it’s not my application of choice. My apologies. 😦
