Justin Timberlake Makes Historic Debut on Mainstream Top 40 Chart, Taylor Swift Hits No. 1

Justin Timberlake's "Suit & Tie" (RCA), featuring Jay Z, makes a record-setting debut on Billboard's Mainstream Top 40 chart, which measures pop radio airplay, as monitored by Nielsen BDS, soaring in at No. 14.

"Suit" logged 6,045 plays in the Jan. 14-20 tracking week, with spins on all 157 of the Mainstream Top 40 chart's reporters, pushing it past Lady Gaga's "Born This Way," which opened (also at No. 14) with 4,602 plays the week of Feb. 26, 2011, for the highest debut-week plays sum on Mainstream Top 40, which launched the week of Oct. 3, 1992. (The chart panel expanded from 141 to 157 reporters late last year.)

With its No. 14 arrival, "Suit" takes over as the highest-debuting song by a male artist in the Mainstream Top 40 chart's archives. It bests the No. 19 entrance of Jon Secada's "If You Go" the week of May 14, 1994. Among all acts, only Mariah Carey's "Dreamlover" launched at a higher rank (No. 12, Aug. 14, 1993); "Suit" and "Born" now share the mark for the second-highest lift-off among all artists.

Aiding the fast start for "Suit," several Clear Channel Media and Entertainment-owned Mainstream Top 40 panelists gave it top-of-the-hour plays last Monday (Jan. 14), while CBS Radio reporters played it heavily on its first day and stations in the Cumulus chain added it to rotation.

Based on its first two days of airplay when the Billboard Hot 100 airplay/sales/streaming hybrid chart was tabulated on Wednesday (16), "Suit" debuted at No. 84. With a full week of airplay and sales, projected to reach upwards of 350,000 in opening-week downloads, the song could vault into the Hot 100's top five when the chart is refreshed on Wednesday (23) this week.

"Over the years, we've come to expect the unexpected with Justin's music, which I think is fantastic," says Sharon Dastur, PD of Mainstream Top 40 WHTZ New York. With its retro-soulful vibe, "'Suit & Tie' doesn't sound like anything else out in pop music right now and we can certainly use those kinds of songs. We welcome Justin back with open arms."

"Suit" concurrently roars onto the Rhythmic airplay chart at No. 14 and Adult Top 40 at No. 22.

 'KNEW' NO. 1: Timberlake doesn't have a lock on the week's airplay chart headlines, as Taylor Swift's "I Knew You Were Trouble." (Big Machine/Republic) lifts 3-1 on Mainstream Top 40. The song marks her second leader on the list, following "Love Story," which topped the Feb. 28, 2009, tally.

As it tops Mainstream Top 40, "Trouble" bounds 11-5 to become her Swift's sixth top 10 on Adult Top 40 and debuts at No. 29 on Adult Contemporary.

"Trouble" ranked at No. 4 on the Hot 100 last week with the chart's top Airplay Gainer award for a second consecutive week. It rose as high as No. 2 on the chart two weeks earlier.
