A word of advice those freeware apps (CAP, EAC, CCD Lock etc.) work by currupting the TOC (Table of Contents) of the Audio CD-DA.
The danger here is they won't play in DVD players, PCs, MACs or certain CD players such as car players or ones that read MP3s and people can still copy them. So you wind up with a currupt Audio CD that won't play in PCs or DVD players and crash MACs!
These apps do NOT work, all they do is curupt the CD and lower their compatibilty. There is no free-way to protect CD-DA with near 100% compatibilty, that costs money.
As long as you are aware of this and don't mind that only standard CD players will work (which most people don't use anymore) then do it.
