Relating to the bolded text quoted above, is the tape drop out at the beginning of "Black Cow" on Steely Dan's Aja fixable? It is on every single mastering of the album I have ever heard and I assume it is part of final mix and unchangeable. That is the technical question. The aesthetic question I also have is whether you would fix that if you could. I mean it seems to be patently a mistake. But I have lived with that mistake now for around 40 years across multiple versions of the album. I think it would sound totally weird to me now if it were gone. But taking that logic to the extreme, I understand one would never correct or improve anything. Curious as to your thoughts as I feel at least in that particular example it should be left alone even if it were correctable.
