There are different ways to replicate a CD. One way is to load the content of the disc onto a music program on your computer. (iTunes, Windows Media Player, Matchbox, Java, etc.) Then, once it is on your computer, most programs will allow you to select what you want on the new CD and simply burn another CD. You have to make sure you are using the right type of CD, though. (Cd-Rom, DVD-Rom, etc)
