wmusic is a WindowMaker dockapp by Bastien Nocera.
Basically, the controlling dockapp that comes with XMMS - called wmxmms - sort of stinks. It only has control buttons.
wmusic has much more. Not only it has control buttons, but it also has track time display, playlist position display, bitrate display, and last but definitely not least, the feature that makes wmxmms to pale in comparision...
...the "Super stylee rotating arrow"!
