Yes, given that Leia can't really know what she's recalling, "just feelings" as she says, it's vague. Either way, we know she didn't know her mother. I wouldn't change any music to prequel music unless the piece I was replacing was particularly unsuccessful as it stands. I hate homogenising everything into one identical lump. Somewhere in the 12 years since the Special Editions people have started to want that, whereas I prefer each movie to have its own aesthetic, its own identity. So what if Imperial Shuttles never appeared before Jedi and then they're everywhere. We didn't see A wings or B wings, Mon Calamari and their cruisers, and any number of other designs before they featured, but so what? Seeing new designs actually used to be something that appealed about these movies.
