Example Input: Consumer warning - critical flaw in mastering . The charming 1977 musical is not the subject of this note. The show is great and the liner notes are superb. However, consumers should note that there is a critical flaw in the mastering (at least on the disc version that I obtained). It is very unfortunate that the manufacturers did not pull this mis-mastered version from the market. As noted elsewhere (and absolutely correct), an entire track of sound is lost and can only be heard distantly in the background. If the problem is corrected and later discs are OK, it just compounds the problem with no way to know if you have a flawed disc or an OK disc. A most unfortunate problem for what should be a joyous recording
Example Output:
NEG
