The hassle is purely because sd was designed with digital rights management encoding to prevent copying and protect copyright owners. If the sd system would have taken off you would have seen many more professionally produced karaoke mp3s and midis on the market to suit. However not unnaturally drm is unpopular with customers and anyway beaten in the marketplace by Apples protected itunes system which virtually took over the world.

Nevertheless I have a large card full of Sunfly karaoke dvds and playing along to a cd quality recording of the original backing arrangement exactly as on the original song minus the vocal quantum beats any keyboard style hands down. Particularly since you can synchronise the sequencer to the audio and multitrack.

As I've said many times just treat Jukebox as transfer program to get audio on the card and it is quite bearable for the gains involved.
