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?
My fave too as it's closest to foobar, critically with the tagging interface I prefer. Have you added any additional plugins to your install? I tried adding a few (music library, Discord Rich Presence) but must be the right sort of stupid not to understand the instructions. facepalm
