Using Audacious 3.2.4 here, rebuilt from source with a few different build options.
Here's what it looks like (scroll down the page a little):
I've been a KDE/Amarok user until this summer, but I ended up getting tired of the little bugs here and there, with Amarok having me regularly force-rebuild my collection and everything.
Before that, I've been a die-hard XMMS user for about ten years, but nowadays, its GTK1 interface seems anachronistic like an East German prison. I've regularly tested Audacious, but first versions were quite horribly buggy and segfaulted all the time. This version is now rock-solid and has a nice set of features. Plus, it's built to play about every audio format under the sun. I can only recommend it.
