The group reigns more than 12 years after its first week on the tally.

Panic! at the Disco scores its first No. 1 on a Billboard songs chart, as "Say Amen (Saturday Night)" jumps 2-1 on the Alternative Songs airplay survey dated June 30.

With 12 years, four months and two weeks between its first appearance and its leader on the list, the Brendon Urie-led band ends the fifth-longest wait for an initial No. 1 in the chart's nearly 30-year history.

Stone Temple Pilots went the longest between a debut and first No. 1 on Alternative Songs: 17 years and two weeks between "Plush," in 1993, and their first (and sole) leader, "Between the Lines," in 2010.
