GROOVIE: T7G CD audio (flac) not in sync with intro animation

I noticed that the crashes of thunder that are part of the redbook audio track that plays over the logo and title animations don't sync up with the video.

Anecdotal, but I remember The lightning that shows behind the mansion during the title animation and thunder sounds from the redbook audio track syncing up on original hardware. I guess this was never 100% precise, as speed-sensitive loading of data is involved, but I do think it was a lot closer at least than with ScummVM.

I also noticed that the presence of a pregap and lead in of the audio track varies between versions of the game, but I suspect the original US first release that has the music starting more or less on 'second 0' that I used to rip my flacs from, should be accurate.
