"Roar" becomes Perry's eighth Hot 100 No. 1. She first led with "I Kissed a Girl," which began a seven-week command (her longest) the week of July 5, 2008. In that span, Perry has quickly scaled the list of the women with the most No. 1s in the chart's 55-year history. Among female soloists, only Mariah Carey (18), Madonna, Rihanna (12 each), Whitney Houston (11) and Janet Jackson (10) have totaled more leaders. Among all artists, Perry is one of just 16 acts with at least eight No. 1s; the Beatles lead with 20 Hot 100 toppers.
Not related with "Roar", but with the 2013 charts: "Blurred Lines" passes "Thrift Shop" in points accumulated throughout the year; becomes frontrunner for song of the year.
