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?
YES, foobar2000!
I also gravitated towards Audacious, but I foobar2000 was 10/10. Might consider running it through Wine, since Audacious is not quite there unfortunately
