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?
Seconding this. MPD + ncmpcpp + an MPRIS plugin. With the latter I can control the music playback through global keyboard shortcuts and the system tray UI if necessary.
