I'm sure that I'm not alone here, and this isn't really that much of a confession, but I still pronounce Copy Of A with the letter A in mind, as opposed to the actual word. I think I pronounce the word when I'm speaking about it though, but that hasn't been an issue since I don't really have that many people to discuss Nine Inch Nails with in real life though.
Anyway, yes, it still throws me off from time to time, until actual song reminds me not to say it that way. Oh, and sorry if I repeated myself, as I have a feeling that I've already mentioned it. However, it just occurred to me again, because I still caught myself doing that.
