Was iTunes importing the CD (the same one from the other thread, perhaps?) and you were listening to it at the same time? If so, it makes a lot of extra noise because it has to skip back and forth between the point at which you're playing it, and the point at which it is currently importing. What's probably better is to wait until the first song imports, and then select the album in the itunes library and play it from there -- as the songs import, they will add to the list and it will keep playing, and the disc won't have to skip back and forth.

If it wasn't importing at the same time, there is some variation I have seen based on how well-balanced the disc is. Sometimes discs are slightly warped and they can play, but they make a lot of noise. I have seen this on Windows laptops too....
