Elle King crowns Billboard's Alternative Songs chart (dated Sept. 19) as "Ex's and Oh's" rises 2-1. With the ascent, she becomes just the second female solo act (with lead billing) to top the list since 1996.

In the airplay chart's 27-year history, King's debut hit, released on RCA Records, is just the 11th song by a lead solo woman to command the tally.

"I'm honored, excited and completely dumbfounded, emphasis on dumb, because I never thought my song would ever be No. 1 of anything," King tells Billboard. "I'm just so grateful."

King follows Lorde, who broke a 17-year streak of male and group leaders when her debut hit "Royals" led the chart for seven weeks, beginning Aug. 24, 2013. Until then, Tracy Bonham had been the last lead female soloist to hit No. 1, nearly 17 years earlier with "Mother Mother" (for three weeks in June 1996).

Women's voices haven't been entirely absent from the chart's upper ranks over the last two decades. Female-fronted groups like Evanescence (led by Amy Lee), Florence + the Machine (Florence Welch) and Paramore (Hayley Williams) have logged top 10s. Female soloists have also appeared as featured acts on such hits as fun.'s "We Are Young" (Janelle Monae) and Gotye's "Somebody That I Used to Know" (Kimbra), while bands like Of Monsters and Men have mixed male and female vocals on their top 10s.

Of the 330 No. 1s in the Alternative Songs chart's history, here are the only leaders by solo females (with lead billing):
