I've seen quizzes like this where the Quizmaster automatically fills in soundtracks, compilations, etc., but I don't know how to do it or if it's even possible for user-created quizzes. Thanks for the comment, though, and for taking the quiz!
This isn't an exhaustive list of all albums that went multi-platinum, just selected ones. All of the albums on this list, however, have achieved "diamond" certification for going 10 x platinum or more. Thanks for taking my quiz! ;)
