There are now some plugins for players like Windows Media and Winamp which helps user to send information (what song he/she is listing to right now) to a page on the Internet. I have previously used a jukebox called musikCube which allows one to send now playing info either to a remote site, local file or launches a external program with command line parameters. It would be plus for Jajuk (as i see it), if there is something like available.
