Why can my car radio play my protected audio CDs when my DVD-ROM cannot read it?

Audio CDs often do not conform to the Redbook standard. Often they have somehow exotic data structures; The error correction that is built in the reader often tries to correct the structure and falsifies it (that's the trick of audio copy protection). Sometimes it cannot even identify any CD in the drive. If the error correction cannot be disabled and the drive does not understand the content on the CD, CloneCD can do nothing to make it readable. That's a hardware issue.
Car CD players and standalone CD players just filter out the errors and do not try to correct them. So you are able to hear music.
CD drives in PCs are more fussy as they do not try to filter out the errors. They want to read and write corrected data errors.
Generally CD writers read audio CDs more reliably than DVD-Roms. But even writers that read almost all CDs are rare.
