Those numbers give Red Velvet their biggest sales week ever in America, giving them a new peak on Heatseekers Albums (which sees far few K-pop acts entering the ranking) and their ninth Top 5 entry on World Albums (the group has four No. 1s which ties them as second-most among all Korean groups).
Indicating healthily growing stateside interest in America, Red Velvet had remarkably just earned their previous best sales week for an album in August with their Summer Magic EP and now earns their fourth consecutive album to score a new, best U.S. sales week after more than a year of growth following 2017 releases Red Summer and Perfect Velvet.
Red Velvet also score their first No. 1 on Billboard's World Digital Song Sales chart with RBB's title track. "RBB (Really Bad Boy)" sold 2,000 downloads in the U.S. in the week ending Dec. 6, according to Nielsen Music. The funky, R&B-flavored stomper and its Halloween-themed music video had 2.7 million on-demand streams (audio and video) combined in the tracking week too.
Red Velvet is now just the fifth K-pop girl group and ninth group total to hit No. 1 on the World Digital Songs chart. Previous to "RBB (Really Bad Boy)," Red Velvet had peaked as high as No. 2 on the tally, earning eight top 5 singles on the chart. Their best sales week for a song came earlier this year via February's "Bad Boy" that sold 4,000 copies in its first and is 2018's 18th-best selling K-pop track in America according to the year-end World Digital Songs chart.
