Tauon Music Box is minimalist and is also probably the best open source Spotify player.

Sometimes I'll just run Spotifyd and control it with my phone.

I settled with Navidrome. It solves 2 use cases for me. Due to being web based it can be used by any PC or mobile device with access to my server. Additionally it supports subsonic which allows me to use a native android app (ultrasonic) and have music on the go. I don't use services like Spotify.

I use Sonixd as the frontend to my Navidrome server, and it's the bees knees.

Winamp or xmmp/qmmp.

Sayonara.

Mpd has always served me well. I use ncccmmmmppp (however its spelled) to manage playlists and such. For album artwork I run sxiv pointed at file in /tmp/. I forget how that part works, actually. I have a grid layout on a second monitor, so I just square up the mpd client and sxiv. Doesn't look too bad.

Semi-related, but as a project I ripped out the pressure/impact pads of an old midi keyboard for use as prev/(pause/unpause)/next buttons, so if the song sucks I can literally punch my desk to skip it.

Quodlibet

I used to use Strawberry, but my collection has grown enough that I can't just sync it everywhere, so I use Jellyfin now. I still use Strawberry's library management to move files into album artist/album/00 - track.ext though. Someday I'll dig into id3v2 to just write a script instead.

Logitech Media Server, followed by strawberry, quod libet, rhythmbox

Quod libet starts to act funny with 50,000 flac collections. Rhythmbox too. LMS is still chugging at 100k and I can get it on any room in the house, across 2 clients on computers, 2 on raspberry pi and my android phone. If I want to listen to 24/96+, Strawberry can handle it all although I haven't warmed up to the interface. Volumio sucks, it's way too slow.

Spotifyd

mpd+mpdevil

Feishin for me and occasionally strawberry

navidrome + ultrasonic

I used to download my music with NewPipe and listen to it on Musicolet, but since then, i just gave up and got a cracked spotify client

Dolphin + mpv for me so I can see the album covers and metadata and see whats available, if I have a specific song in mind, then ill just use the terminal and mpv.

Schism Tracker

i use foobar because i can't live without dolby headphone

Plexamp all the way, easily the sexiest music player I've found so far. All my music is FLAC pulled from Deezer, and since I've got a very large list of artists tracked, it's super easy to discover new music with the radio and sonic analysis features. It's also got a last.fm integration, which gives me more data than Spotify would about my listening habits.

The only feature I'm really missing in it is collaborative playlists. I can share playlists out to anyone on my Plex server, but they can't add or remove songs.

Foobar2000 has been here for YEAAAARS, and I don't think there is a good enough equivalent for linux, and by that I mean playlist tabs, global shortcuts, etc

Mostly CMUS. Clementine on rare occasions.

I have to say Supersonic.

It's a Subsonic player that integrate with my Airsonic instance in Docker.

It requires a backend like Airsonic, Navidrome etc. It's not a stand alone player.

Couldn't find any that works for me. At the moment I just play my music in mpv from terminal.
