You are ripping the song of the orignal CD.

By copying CD's songs the recording industry loses money, of course this is recouped by a tax which is place on all blank CD's. But in effect you are "ripping off" the Recording companies by having an addtional copy of the song and not paying for it. And then of course if you share your music online as so many people do, the companies lose even more money. That's why it's called ripping. Remember it all starte with napster.
