The chart accomplishment is the first time a K-pop album has spent multiple weeks atop World Albums.

Making a strong case as the K-pop act to watch in America, BTS manage an unprecedented feat as their latest album earns a second week atop Billboard's World Albums chart.

In its sixth week, the boy band's The Most Beautiful Moment in Life, Pt. 2 zooms from No. 6 to No. 1 on the chart for its second, non-consecutive week atop the ranking. While many Korean acts have topped World Albums in the last few years, BTS is the first K-pop act to have the same album spend more than one week on top.

The feat is also notable after Pt. 2 bowed on the Billboard 200 when it dropped in December, the first appearance for a K-pop act that isn't under SM or YG Entertainment -- Korea's two biggest record labels.

BTS fans clearly got a lot iTunes gift cards this holiday season as the septet has two more entires in World Albums' Top 10: The Most Beautiful Moment in Life, Pt. 1 returns to No. 4 (after peaking at No. 2 earlier this year) for its 10th, non-consecutive week on the chart. Meanwhile, their 2014 full-length Dark&Wild flies back to No. 7 (after peaking at No. 3) for its 10th, non-consecutive week on the chart. A slew of boy bands including EXO, GOT7, Seventeen and iKON also hit the chart, but BTS reign supreme this week.

Billboard recently named The Most Beautiful Moment in Life, Pt. 2 one of the best K-pop albums of the year, while we also named its lead single "Run" one of the best songs in K-pop from 2015. The group recently ended domestic promotions for the LP.
