Best-Selling Albums of All Time Quiz

Every album credited with 20 million or more in reported sales worldwide, from the industry's certification records. Name each one with the artist and release year as clues, pick the genuine 20-million seller from a group of real Billboard year-end number-one albums that never got there, match each album to the artist credited with it, sort a selection by certified copies, or tap the members of each sales band out of a grid. Where a title is too generic to identify a record on its own the artist is shown alongside it, and three albums here are titled the same thing. Reported figures are round press claims, so the ordering round uses the stricter certified totals instead; no answer is named here.
