Yes, they play ok in Quicktime but I dont like to use Quicktime for music because I can only get one track to play by selecting the individual track then it doesnt automatically roll on to the next track. I dont have that with iTunes.

Basically, I have on my Mac hundreds of audio files which I transferred from my old PC. I thought I would have full functionality. But maybe Im better to start from scratch again and copy from the original CDs?
