#13 – 18,000 UNITS
Adele – 21 (2011) : 1,870,000
A modern-day classic, Adele album 21 enjoyed a strong rebound thanks to the late 2015 release of 25. Selling well enough to be part of the Comprehensive Chart during the first 18 weeks of the year, the album struggled much more to complete the season in a good way, never featuring inside the Top 80 Catalog Chart for the last 28 weeks of the year. At this current rate, year 2017 is going to be much weaker. In any case, the cumulative tally to date of 1,87 million copies sold is absolutely superb.
