NEW YORK, April 2 -- BTS has landed 13 songs on the Billboard Hot 100 this week, with "Swim" debuting at No. 1 on the chart dated April 4.

Seven of the new entries sit in the top 50, with "Body To Body" (No. 25), "Hooligan" (No. 35), "FYA" (No. 36), "Normal" (No. 41), "Aliens" (No. 47) and "2.0" (No. 50) joining the title track in the chart's upper half.

In total, 13 of the 14 tracks from the group's fifth studio album Arirang made the main songs ranking, with only the interlude "No. 29" - built around the toll of King Seongdeok's bell, a registered Korean national treasure - missing out.

The latest haul lifts BTS' career tally on the Hot 100 to 39 songs, nine years after "DNA" first sent the group onto the chart.
