Rob, I've explored the possibility of using the disk in the kn6000, and while it does load up and play in direct play mode, it didn't do much for me. The disk uses an old dos format on a double density disk which foils most attempts to copy the disk with new disk drives. The music is just fine, but if all a person can do is listen to the music, then I would suggest an MP3 file, or a music CD. It's much cheaper. By the way, the piano disk I examined was "Danny Wright's Christmas". Hope this helps.
