The boy band can now boast the title of K-pop act with the most weeks at No. 1 on the chart.
A fourth week at the chart's summit means BTS sets a record for most weeks atop of World Albums by any K-pop act. Previously, fellow boy band B.A.P held that title, sending three different titles to No. 1 on the chart for three separate weeks -- One Shot and Badman from 2013 and First Sensibility from 2014. While BTS has only had one chart-topping album, the fact that it's stayed atop for four weeks lets the act surpass B.A.P in total chart-topping weeks.
