Here is a Yad script for system tray radio player.
( requires Yad, Mplayer - libnotify optional )
Right mouse click tray icon for menu:
Station List: Available station > select one to play
Station Add: Add a new station > Name - URL
Play / Pause: Play pause current station
Stop: Stop Playing Station
Quit: Exit Trdo
If you have libnotify installed - an on screen notification will be displayed when selecting stations - also left mouse click on Trdo icon will also show on screen notification with current station playing.
Notifications could be changed to osd_cat or yaf-slpash i suppose.
