March 29: Justin Bieber tweets this pic of Taylor Swift after "punking" her on MTV's "Punk'd."

J ustin Bieber, Taylor Swift and Jennifer Lopez storm Billboard's Nielsen BDS-based Pop Songs radio airplay chart with new singles, led by Bieber's record-breaking bow.

Bieber's "Boyfriend" launches at No. 20 with 3,961 first-week plays on 129 of the chart's 134 reporters (an average of 31 plays per station), marking the best first-week plays sum for a song by a male artist in the chart's almost 20-year history. The song also ties for the seventh-best positional start among all acts in the tally's archives.

The arrival of "Boyfriend" is all the more impressive given Bieber's track record at Pop Songs, where the teen star has yet to log a top 10. Despite his sales success (8 million albums sold, according to Nielsen SoundScan) and high social media profile (19 million Twitter followers), Bieber has charted only as high as No. 14 with debut hit "One Time" in 2009.

"Boyfriend" is set for a likewise lofty launch on the Billboard Hot 100 this week, aided by approximately 400,000 first-week downloads, according to industry projections. Check Wednesday (April 4) for the earliest highlights of the Hot 100 and Digital Songs charts.

THR: 'Punk'd' Premiere: Justin Bieber Tries to Make Taylor Swift Cry

SWIFT START: Repeat ACM Entertainer of the Year winner Taylor Swift scores her highest Pop Songs debut, as "Eyes Open" bounds in at No. 28. The song, from the soundtrack "The Hunger Games: Songs from District 12," which debuted at No. 1 on the Billboard 200 last week with 175,000 copies sold, according to SoundScan, starts even higher on Adult Pop Songs (No. 24). The debut is the Adult Pop Songs chart's highest since Dec. 13, 2008, when the Fray's "You Found Me" began at No. 19.

"Eyes" arrived as the Hot Shot Debut on the Hot 100 last week at No. 19, fueled by a No. 4 entrance on Digital Songs (176,000 downloads sold).

Jennifer Lopez completes the Pop Songs chart's trio of debuts, as "Dance Again," featuring Pitbull, shimmies in at No. 34. The pair teamed last year for the No. 5-peaking "On the Floor" on Pop Songs (a No. 3 Hot 100 hit), Lopez's first top 10 since 2003. The video for "Dance," available in the iTunes Store as of today, will premiere Thursday (April 5) on "American Idol."

Pitbull, meanwhile, is readying his own entrance on Pop Songs. His solo single "Back in Time," from the forthcoming movie "Men in Black III," is bubbling under the survey after its first week of airplay.

All rankings, including the Hot 100, Digital Songs and Pop Songs, will be refreshed Thursday (April 5) on
