All burned music CDs are likely to have errors. When the data is written. some numbers in the stream are burned incorrectly. Each individual burned music CD is likely to have different errors.

Thus went down in flames for a good technical reason, the plot of a novel I was planning which involved each spy having a disk of music to use as a key for encrypting and decrypting messages...

On music playback, the CRC fixes many errors - but for music it is likely that you will not hear any problems (data is of course a different matter!).
