We all have the same stereo, I don't understand why some cannot play burned CD's. Could it be the recording process, or how the original was created? Maybe the stereo's from 04' to 05' and 06' is different in the playback? Maybe it's the type of CD being used? I know DVD+ and - is tricky on some machines, are some CD's the same? I haven't played a CDRW in my car, I don't know if it would work or not.
I'm not into the electronics of stereos etc, so I am somewhat ignorant to the functions. I would assume some prerecorded CD's, like movies are copy guarded? I haven't had a problem with any burned music from Limewire. I am recording older classic rock music though, not the new junk, top 40, or hip hop rap crap that is out there. Maybe the newer music from current artists is copy guarded?
My dad once said, if you cannot whistle a tune to it, it ain't music. How do you whistle a tune to rap?
