I have tried them all and EJukebox is the best jukebox software!
It does everything I need, plays all music and video files, lets me customize the interface how I want and lets me set criteria for random song playback when the playlist is empty.
Plus i discovered if you ask in the audiosoft.net forum they actually add your requests...most of the time to the next EJukebox version.
There is even the EJukebox 2Web feature that lets me use my mobile phone's web browser to remote control my collection.
The EJukebox homepage/download is located here: http://www.audiosoft.net
