Once when I was talking to DJ Qbert (the world's most phenomenal skratch DJ), he was battling a CD skratcher. He says the things don't sound a thing like vinyl. it's a cold hard digital sound. i heard the things myself too and it'll be awhile before they're accurate, but even if they are one day, they'll still be a little off with the digital sound it produces.

Plus: CD Dj's get the easier options like looping and auto-beatmix while it takes more skill to do the vinyl.

I just hope one day computers or robots don't become DJ's that easily beatmix and stuff. I would die!
