Britney Spears is now the second artist in the Billboard Hot 100's 52-year history to debut multiple songs at No. 1, as "Hold It Against Me" blasts in at the summit this week.
Spears debuted at the top with "3" the week of Oct. 24, 2009. She joins Mariah Carey as the only acts to arrive at No. 1 more than once. Carey made grand entrances with "Fantasy" and "One Sweet Day" in 1995 and "Honey" in 1997.
(All charts will be refreshed tomorrow (Jan. 20) on Billboard.biz).
"Hold It Against Me" is the 18th song to debut at No. 1, and the first since Ke$ha's "We R Who We R" the week of Nov. 13, 2010.
The track is Spears' fourth No. 1 on the Hot 100. Prior to "3," she reigned with her debut single "...Baby One More Time" (two weeks, 1999) and "Womanizer" (one week, 2008).
"Hold It Against Me" starts atop Digital Songs with 411,000 downloads sold, according to Nielsen SoundScan. As previously reported,  the sum marks the highest debut frame by a lead female artist, besting the 325,000 shifted by Taylor Swift's "Today Was a Fairytale" the week of Feb. 6, 2010.
On Hot 100 Airplay, "Hold It Against Me" begins at No. 23 with 45 million first-week audience impressions. The song's No. 23 entrance is the chart's best since Mariah Carey's "Touch My Body" began at the same rank the week of March 1, 2008.
The strong start of "Hold It Against Me" on Hot 100 Airplay is fueled by the song's embrace by pop radio. The cut enters the Mainstream Top 40 airplay chart at No. 16 with 4,071 plays, the highest detections total by a debuting entry in the latter chart's 18-year history. "Hold It Against Me" also ties Madonna's "Frozen" (No. 16, March 7, 1998) for second-highest launch in the list's archives. Only Mariah Carey's "Dreamlover" began at a higher rung, having rocketed in at No. 12 the week of Aug. 14, 1993.
"Hold It Against Me" received airplay on all 130 reporting stations in the Mainstream Top 40 chart's tracking week (Jan. 10-16). The song's first-week airplay translated to 36.4 million listener impressions, the week's 10th-highest mainstream top 40 audience total.
