This may be true of random data but I am not sure it is true of music and perhaps even less so of an mp3 file. I wonder if you change 1 bit in a wave file how many bits change in the resulting mp3 file? In a video mpg file because of the index and difference frames a small change would propagate through many following encoded frames. This should make it more likely that intermitant crcs would catch a change.

However, it still seems likely that a rerip to correct a single skip in a song could easily be missed. Somone should probably run a test.

On the other hand I would be perfectly happy to flag my ID3 files on rerips if we could create a standard for that??

Cheers,
