My year old iMac rejected music CD (new but Copyright 1989) and an older (1995) CD-ROM. Works find on newer CD-ROM and I just recently burned new DVDs with it. On another music CD, iTunes insisted on copying it, and then would not play it. I did a force quit. I am a former Windows person and used to a "normal" CD player program. What is the problem? The SuperDrive, the CDs, iTunes, or me?
