I'm not thrilled by the music player options on Linux. I've tried many and found most of them awful. Even the author of this article notes negatives about all of the listed players, which I find unacceptable (except for Recordbox, I'll have to look at that). And these are their favorites out of 200 players!

It's the typical problem of free software: bad UI.

I use Music on macOS (disable the music store and it's fine) and have used Rhythmbox on GNOME (passable). Still looking for something good on Linux.

List from the post, with the author's own criticism:

Amberol

This barely fits my criteria for features … no library management

Euphonica

you will also need to set up MPD … The UI chokes … wish it had a song search function … changing the volume requires using my scroll wheel on the volume knob

Feishin

You will need a music server … Electron app

Lollypop

the user experience is painful

Plattenalbum

you will need to bring your own MPD … cannot even see a list of all albums

Strawberry

less intuitive than I’d like it to be … giant translucent strawberry in the middle of my screen at all times

Tauon

“everything-is-a-playlist” approach … overwhelming and confusing … stretched icons … scroll bar is on the left of the window for some reason
