Karaoke is a registered version feature as shown here. You can purchase a registered version (no nag screen and enhanced features - go here for purchase information. Setup for the Karaoke feature is pretty simple - if you have the files supported, you merely access the Karoake section of the configuration, set the path to your karaoke files and the behavior of clicking to queue or play the file. If you are looking for a good frontend that allows you to play games through some of the best emulators, HTPC integration with Windows Media Center, watch videos, or, Karaoke, and support forums and members second to none, then I heartily recommend paying for a registered copy!
