A CD getting scratched isn't really a bug, it's a limitation of that technology and form factor. Is there anybody on earth that didn't scratch up at least a few accidentally?
It is a bug when the battery compartment is inside CD tray so if the battery flap isn’t shut flush you end up with damaged discs. This isnt normal operation of CD players, it’s a problem with the design of the unit.
That said, it was still one of my favourite portable music players because it sounded amazing and supported MP3 CDs too.
