Foobar2000:Components/Advanced Controls (foo advancedcontrols)
Control all the playback functions of FooBar2000 from icons in the Taskbar Notification Area (that is - the tray)
In a very small space (2 tray icons wide), you have the playback functions (Play / Pause, Stop / Load, Previous, Next) and the seeking bar. Plus, a right-click menu with all these functions, and more!
The component also provides a popup balloon with the current song's information, a hotkey to delete the file that is currently playing, skinnable icons, etc.
Try it, you will like it.
