Group BTS has shown signs of going backward on Billboard's main album chart ahead of their comeback.

According to the latest chart released by Billboard on Jan. 22, MAP OF THE SOUL: PERSONA ranked 172nd on Billboard 200, which was released by BTS in April last year.

This is a slight increase from the 176th place recorded last week and is still a steady favorite ahead of the release of a new full-length album. The album has been on the charts for 22 consecutive times since it first topped Billboard 200 on April 27. 

In addition, MAP OF THE SOUL: PERSONA is showing a unique presence by ranking first on the charts, 18th on the "World Album," 21st on the "Top Current Album" and 30th on the "Top Album Sales."

In addition, BTS remained at the top for 132 weeks in a row in Social 50. It is the 162nd time that they have maintained their own record, the longest ever on the Billboard chart.

Meanwhile, BTS will release their fourth full-length album "MAP OF THE SOUL: 7" on Feb. 21.
