Mine is Strawberry since it has a ton of options and plays a ton of formats. It's also (distant) fork of Amarok 1.4 and integrates well with KDE Plasma. I'm curious what other people are using these days. What's your favorite player?
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.
