TBH the only thing I care for (except maybe for playlist management) is gapless playback. There's no word about it, but I constantly find out that the new players do not really care about the gap, while the music I am listening to is always ripped from my personal CDs and they mostly have music continuing on two or more tracks. Why nobody cares about it?
Do you know this feeling when you get towards the High Hopes on The Division Bell and there's this ugly crack in between tracks?
There is a music player called Gapless that might help :) https://github.com/neithern/g4music
Also https://github.com/vicrodh/qbz for Qobuz supports gapless playback
My guess is not everyone is annoyed by that, or knows about the option. It was a nice surprise of qmmp, it switches to the next song without an extra pause.
I use it with a winamp skin from https://archive.org/details/winampskins, to add to the options. Not sure about streaming support, I use it with local files.
