In addition to what the sibling says, CDDA discs have less error correction than CDROM discs. Each audio sector (frame) carries 2352 bytes of audio data, while a data sector carries just 2048 bytes of data; a different coding is used to reduce bit errors, at the expense of storage capacity.
On top of that, the audio extraction mode (in the drive) is usually optimized for constant-time delivery rather than accuracy; if an audio sector is damaged, most players will opt to deliver inaccurate data rather than stop the audio stream altogether.
