Which software organizer & songbook maker is for CD+G?
There is an application called Song Book Creator. You can download a trial version of the software from its official website. Alternatively, use a dedicated karaoke application that might suit your needs for this operation. It's called FastTracks V2 and it's available from the developer's page as well. Personally, I would recommend FastTracks V2 because is capable of managing almost everything when it comes to karaoke.
