too bad that's not the defintion of a burnt CD. A burnt CD simply means duplication. Maybe 8 years ago you might have had a valid argument (your definition would still be wrong however) but with hard drive sizes and Internet speeds increasing, Lossless codecs like flac,alac, and ogg becoming more prevalent, The idea that burnt CDs just don't "slap as hard" Is just plain ignorant.
Btw I can tell the difference between 320 k mp3s and an aiff, lots of other people can too.
