I've been a professional musician for almost 25 years, have recorded in, worked in, and even owned studios, and I've never once heard a studio referred to as a "stu". Just to be clear, I enjoyed the puzzle and I found it challenging but fun. But that's not an industry term pros (or even amateurs) use whatsoever.

I'll preface this by saying I enjoyed the puzzle, I thought it was brilliant, etc. etc. I'm not complaining. Just a thought on 64D, "keys above Cs"... The way it's clued, it kind of implies that you're moving UP chromatically, from C on your instrument. When you go UP, you move to a sharp. You don't move UP to a flat. Which would give you a C#, not a Db (which doesn't fit of course, but that's not my point). Yes I understand C#/Db are enharmonic names for the same note, but perhaps it would have been better to say "keys next to Cs" or something else that doesn't imply upward musical movement.
