Check for control panel/extension conflicts by restarting with only the CD extensions and control panels installed. The Extension Manager can exclude all but the base System 7.5 extensions.
Usually this behavior can be attributed to conflicts with software that extends the functionality of the Macintosh file system and its ability to read foriegn file formats. Make sure you have the Foreign File Access and Audio CD Access files in your Extensions folder.
One known control panel that causes this behavior is DOS Mounter from Insignia Solutions. It is similiar to PC Exchange in that it allows the Macintosh to read DOS disks and CDs. If both PC Exchange and DOS Mounter are installed, the Macintosh will have this trouble with audio CD's. Remove either PC Exchange or DOS Mounter.
