No, you can still make as many copies of an *original* as you want.  It does 
not limit this.    Now really, how could you keep track of what cds you had
already copied?  There is the possibility of being billions of different cds
available and there is no organization that assigns id numbers (that I know
of, and I do know that you can go to independant orgs and get a cd pressed).

The limit is on the number of copies of copies you can make.
