Spoiler: Note Since the K-pop industry (SM started the trend) counts album and repack together, I will keep it consistent and do that. Do not shade or bash any artist: selling a lot of albums is an accomplishment either way, with or without a repack. According to numbers from Gaon 2016 and 2017 year-end album chart, 'Wings' + 'You Never Walk Alone' sold a combined number of 1,612,835 -- which makes it, in the K-pop industry's eyes, the best-selling K-pop album since 2002. (Obviously before the digital era, artists sold upwards 2-3M albums without repacks.) If we're talking about only a single album, though, 'Love Yourself: Her' still remains untouched. But I thought I should give some credit to her predecessor 'Wings'. Congratulations, BTS! Spoiler: Omitting For the sake of simplification, I omitted albums from solo artists BoA and Kim Gun-mo. This is all idol groups' albums from 2002 onward.
