Sam Smith and Kim Petras became the first openly non-binary solo artist and first openly transgender solo artist, respectively, to ascend to No. 1 on Billboard's Hot 100 song chart.
Their song "Unholy" debuted at No. 3 on Oct. 8 and spent two weeks at No. 2 before surpassing Steve Lacy's "Bad Habit" on Monday. The song earned both artists their first No. 1 spot on the Hot 100, with Smith's "Stay with Me" reaching No. 2 in 2014.
