There is another recent topic about multiple discs, but I have no idea if that is the same as what I am proposing. This used to be a feature of Adaptec Easy CD back before Roxio destroyed the software (the old versions won't work on newer OS or drives), and I would love to be able to do this again. It is currently a real PITA to do this manually. Many times I would like to create a set of audio CDs for disc changers, etc from MP3s. The way it used to work is that when the first CD filled, the songs would spill to a 2nd and so on. Since I have a 12 disc changer, I could keep adding till I had 12 discs. I could drag songs between discs to help minimize the leftover space. When I was satisfied with the arrangement, the burner would have me put in the discs one by one.
