Why?
A John Williams Star Wars score is kind of a sacred thing, and, though most don’t think about it that way, the Main Title is always a part of the whole - each one should be unique in its own way, like the individual scores themselves. The fact that the PT all use the same recording is a big issue to me (and emblematic of the main problems I have with the latter films’ scores).
From what I recall, Ady’s alternate, while nice, essentially grafts the opening blast of the original film’s Main Title onto TFA’s, which to me is a big no no, as it’s dipping into that PT recycling territory, while also stripping the TFA recording of its individuality.
For and edit that’s supposed to make TFA less of an ANH rehash, this is a change that would feel entirely out of place.
