K-pop's powerhouse quartet also spend their second week on the Social 50 chart.

The world is eagerly anticipating the "blood moon" lunar eclipse this weekend, and Mamamoo's Red Moon is earning the girl group new chart accolades. 

The powerhouse quartet score their best U.S. sales week to date with their new Red Moon EP, which sold 1,000 copies in the week ending July 19 and debuts at No. 4 on Billboard's World Albums chart. Mamamoo have landed six entries on World Albums to date, starting with 2015's Pink Funky (which peaked at No. 7 on the chart), Melting (No. 8) and Memory (No. 12) both from 2016, followed by 2017's Purple (which hit No. 1, their only chart-topper so far), and Yellow Flower from earlier this year (No. 7).

Mamamoo's best U.S. sales week also scores the group their first appearance on the Heatseekers Albums chart -- a ranking that sees far fewer K-pop acts. Starting at No. 25, Mamamoo become just the third female K-pop act to enter Heatseekers this year following Twice and Red Velvet. (It should be noted that Blackpink would have also landed on Heatseekers if their Square Up EP had charted lower than No. 100 on the Billboard 200 since Heatseekers only ranks up and coming musicians that have had albums place below the top 100 of the Billboard 200.)

Following the tone set in their Yellow Flower lead single "Starry Night," the women of Mamamoo continue to embrace a Latin-influenced sound, more in line with larger global trends than the funky pop they broke out with at the start of their careers. What hasn't changed is the girls' continuously powerful performances as they tell off a self-centered lover on their single, while the snappy, trappy "Midnight Summer Dream" boasting energized belts on the chorus and a heavy-handed hip-hop sound on "Sleep in the Car" that sees the members rapping impressively aggressive bars. 

Over on the World Digital Song Sales chart, Mamamoo snap up their fifth Top 10 entry to date with "Egotistic," which starts at No. 5 on this week's chart. The group has eight entries overall with their best-ranked single in 2016's "You're the Best," which peaked at No. 3 in March of that year.

Plus, Mamamoo also secure their second week on the Social 50 chart. The group falls one spot from their debut position of No. 47 last week to No. 48 this week. Still, Mamamoo remain the fourth most active K-pop girl group on the world's leading social networking sites, as well as the fifth most active girl group overall and 15th most active K-pop act overall.
