Chart history

Rapper Eminem's lead-off single (from his album Recovery) "Not Afraid" became the first hip-hop song to debut at the top of the charts since Puff Daddy's "I'll Be Missing You" in 1997, the sixteenth overall in the chart's 52-year history. The same album would spawn another chart topper in 2010 with "Love The Way You Lie" (featuring Rihanna).

Rihanna became the first female artist in the history of the chart to have four number-one singles in a calendar year. She also became the first artist to have a lead single from an album reach number one after its second single when her "Only Girl (In the World)" reached the top of the chart two weeks after "What's My Name?" did.

Katy Perry became the first female artist in eleven years to have three #1 singles from an album. She would go on to have five consecutive and six non-consecutive #1 singles from that album.

Usher became the first artist to score number-one singles in the 1990s, 2000s, and 2010s when "OMG" reached #1.
