I bought this CD's, but it can be burned no audio CD on. I tried it with four computers and repeatedly sounded problems with, zitteren, noise, crack etc. Nu I have many CD's made in vergangenheid but something bad I never get Two sets are for everyone: buy it not. it's lost money. I think not that there are Sony CD's, rather cheap kopieen from China or something, I'm really angry about such a deception.
