Most games from SPC Vision / The Vision Factory have CDDA tracks, but only The Apprentice and Alien Gate play them from the game (only if you use the "NO SFX" setting, though for different reasons in each game). Rhese tracks were mostly intended for people to play on their audio players, which was the primary reason for the CD-i Ready format.
Don't know if either cue sheet for The Apprentice is technically right; CD-i Ready hides the CD-i data in the "pregap" of the first audio track because most audio players skip over that automatically. The first cue sheet is thus technically right, I think.
Edit: Both games always play their out-game music (e.g. intros, highscore, credits) as CDDA, regardless of the SFX setting
