since you can't put the same amount of data on a cd twice without reducing the quality, the audio tracks for the pc will be compressed and won't have the same quality as audio tracks. meaning if you play the cd in a normal player, you'll get perfect quality, while if you play them on pc you will hear 96 kbs wma files, which is total crap. on the other hand, if you download music from kazaa in wav quality and burn them on cd, you can play the cd in perfect quality on all players incl. the computer. this, apart from the fact that downloading music from fasttrack costs nothing. now guess what most people will do.
