World-renowned K-pop group BTS has fallen to 51st on the Billboard main singles chart this week.

After debuting at No. 10 on the Hot 100 chart the previous week, "Fake Love," the main track off the group's third studio album "Love Yourself: Tear," dropped 41 spots, according to the chart Tuesday (US time).

The group's album topped the Billboard 200 main albums chart last week as BTS became the first Koreans to top any Billboard chart. South Korean rapper Psy stayed on the Hot 100 for seven consecutive weeks with "Gangnam Style" in 2012 but never reached the No. 1 spot.

The Billboard Hot 100 ranks the most popular songs of the week in the United States based on radio airplay, digital sales and streaming in the United States.

The boy band also ranked sixth on the Billboard 200 this week, staying on the chart for two consecutive weeks. (Yonhap)
