Tauon Music Box available on Flathub. You look for albums by typing on your keyboard. Once you see the result which says "Artist", hit enter. It creates a playlist which shows all the albums of that playlist. The next time you want to listen to that artist, start typing and select "[Artist name] playlist". This concept differs from a traditional concept of playlists, because it doesn't actually create playlists you can use or export. I just like the UI, although the play controls are bit weird, they don't quite work the way you'd expect them to. It's a new project but worth keeping an eye on.

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.

Winamp or xmmp/qmmp.

Sayonara.

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.

I use apple music. On linux I use Ciderwhich is amazing. Super clean interface and lots of nobs to turn in order to make everything sound and behave the way I like. If you like apple music or are looking for a streaming solution cider is awesome.

navidrome + ultrasonic

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

Considering that I'm using Emby (selfhost), it's able to manage my music collection too and I can play the music from the web player exposed by it.

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

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

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.

I really like Elisa.

I mostly use it to listen to music that's not in my Jellyfin library yet but it does that beautifully.

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.

Schism Tracker

Mostly CMUS. Clementine on rare occasions.

Feishin for me and occasionally strawberry

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
