Katy Perry is officially the first woman ever to have five songs from the same album reach No. 1 on the Billboard “Hot 100.†She had to cut the sax solo from “Friday†to do it, but it was worth it: Michael Jackson is the only other artist to achieve the same feat, with Bad in 1987–88. “California Gurls†was the first song from Teenage Dream to chart, landing at No. 1 on June 19, 2010; “Teenage Dream†followed in September, then “Firework†in December, “E.T.†in April, and now “Last Friday Night (T.G.I.F.)†has taken the top spot. Collectively, the songs have spent eighteen weeks at No. 1, which means Perry’s cartoonish global domination is officially here. Sparkly, revealing dresses for everyone! [Billboard]
