The song caps a brisk four-week rise to the top of Adult Alternative Songs.
Vampire Weekend earns its first No. 1 on a Billboard airplay chart, as "Harmony Hall" ascends 2-1 on the Adult Alternative Songs airplay tally dated March 2.
The song reigns in just its fourth chart week, completing the quickest climb to No. 1 since Nathaniel Rateliff & the Night Sweats' "You Worry Me" also needed only four frames to rule, on Feb. 10, 2018.
Vampire Weekend earns its first Triple A No. 1 nearly 11 years after its first entry on the chart ("A-Punk," April 2008), ending the longest wait for a first leader since Beck took just under 15-and-a-half years between "Tropicalia" in 1998 and "Blue Moon" in 2014, ending the longest delay for a lead artist.
