"Goodbye" marks the second No. 1 for 2NE1 on the World Digital Song Sales chart. It following "I Am the Best," the group's 2011 single and signature song, that topped the ranking for one week in 2014 and another in 2015 thanks to U.S. television syncs and radio play. 2NE1 became the first K-pop act other than PSY to top the chart and led the way for the likes of BIGBANG, BlackPink, EXO, BTS and more to also score chart-toppers.
This is 2NE1’s fifth-largest sales week ever for a song, and second-largest debut week. Their only larger debut week was with "I Love You," when it entered with a little more than 5,000 in 2012. Yet, 2NE1's largest sales week to date still belongs to "I Am the Best" when it sold 6,000 downloads on the chart dated Oct. 11, 2014, thanks to its inclusion in a popular Microsoft commercial.
"Goodbye" caps off a remarkable run for 2NE1 on World Digital Song Sales, becoming their 16th top 10 entry and 20th chart entry overall. Ending with a No. 1 isn't a bad note to say goodbye with at all, but it likely won't be the last time we'll see the 2NE1 women on the charts. CL has been gradually working on her debut, English-language solo album that has the Billboard Hot 100 hit "Lifted" while Minzy is expected to release solo material early this year.
