I checked and found that hundreds of thousands of compact disks have already been released in the US without any warning label they were copy protected. Fatchucks listed some of the known copy-proof CDs. Turns out I had one of them, a Universal CD. I stuck it in my computer -- it brought up its own software to play the songs. It worked. So far, so good.
Next I tried to copy some of the songs onto a custom-mix CD. Everything went fine until the computer tried to write one of the songs to my custom-mix CD. At this point, it crashed my computer.
P.S. I won't be buying any more Universal CDs.
The Doors have recently reissued "remasted" discs of all their albums and yet only the "best of" is listed (and none of the ltd edition concert CDs). Joe Strummer (of the Clash) hasn't approached the top 100 in years and yet his album contains this scheme.
I wasn't too surprised that this list didn't jibe with my buying habits. The labels I buy include Norton Records, Estrus, Sympathy For The Record Industry, Sundazed, Bear Family, and Ace.
