The quartet is also only the second girl group to top both main world-music charts.

BLACKPINK's latest chart accomplishments bring additional accolades that indicates the girl group is on its way to being one of K-pop's brightest acts in America.

With the success of new single "Ddu-Du Ddu-Du" -- which makes history with a debut on the Hot 100 chart -- the group also match records set by some of the music scene's biggest successes. As "Ddu-Du Ddu-Du" debuts at No. 1 on the World Digital Song Sales chart, the quartet now join PSY and BIGBANG as the K-pop act with the second-most No. 1s on the tally. BTS only has more with eight at the moment.

What's notable about the accomplishment is that BLACKPINK has done this in record time compared to the other act's debuts, with the ladies going four for four by snagging No. 1s on the chart for every new release so far, including their debut single.

See a breakdown of the K-pop acts with multiple No. 1s on World Digital Song Sales below.

K-Pop Acts With the Most No. 1s on World Digital Song Sales:

BTS - 8

?PSY, BIGBANG and Blackpink - 4

EXO and 2NE1 - 2

Also notable is how BLACKPINK's Square Up EP is No. 1 on the World Albums chart, which means Jennie, Jisoo, Rosé and Lisa own the top slot on both of Billboard's main World charts. With No. 1s on both the World Albums and World Digital Song Sales tallies during the same week though, BLACKPINK score an accomplishment only three other K-pop acts have managed, including only one other girl group. The only other K-pop acts to top both of the main world-music charts in the same week have been BTS, TWICE and J-Hope.

The following weeks -- and follow-up releases -- will see if BLACKPINK can surpass their seniors, but at the moment they're sitting pretty ("and nasty") among some of K-pop's most accomplished.
