They are the first act to have the year's best-selling album five times since Gaon Music Chart's first full year of tracking in 2011.

BTS' Map of the Soul: 7 finishes 2020 as the best-selling album of the year in South Korea, and one of the seven albums to sell more than a million copies (they have two out of the seven). Plus, the group had now claimed the best-selling album of the year five times, becoming the first act since the chart inception in 2010.

Map of the Soul: 7 sold 4.7 million copies by the end of the year, with 4.1 million coming for the first month.

BTS also logged the best-selling album of the year in South Korea in 2019 (Map of the Soul: Persona, 3.7 million), 2018 (Love Yourself 結 'Answer', 2.1 million), 2017 (Love Yourself 承 'Her', 1.4 million) and 2016 (Wings, 751,301).

Just two of the best-selling album of the last 10 years have been by an act other than BTS or EXO. The latter has the best-selling in 2013 (XOXO (Kiss Ver.), with 335,823 copies), 2014 (Overdose, with 385,047 copies), and 2015 (EXODUS, with 478,856 copies). The only non-BTS or EXO acts with the best-selling album between 2011 and 2020 were Girls' Generation (The Boys, 2011; 385,348 copies) and Super Junior (Sexy, Free & Single, 2012; 356,431 copies).

BTS has three of the top 10 selling albums of 2020, as their most recent album, BE (released on Nov. 20), was the second-best seller with 2.6 million copies and the reissue for their second extended play, Skool Luv Affair, was the year's No. 10 sellers with 670,500 copies.
