This program unpacks the music and lyrics from some LG, Samsung and BBK Karaoke disks for the hardware Karaoke players popular in Eastern Europe and Asia. The music is extracted in its original format, and the lyrics can be extracted in LRC or LRC2 format. You will find it handy when your old Karaoke player malfunctions. Then you typically find out that your player model it is not manufactured anymore, and that the new model comes with a different disk which doesn't have your favorite songs.
