-- Justin Timberlake: "Not a Bad Thing" enters the Hot 100's top 40 (42-27). It surges 29-17 on Digital Songs (62,000, up 59%) and 40-23 on Radio Songs (41 million all-format audience impressions, up 36%, according to Nielsen BDS). On the Mainstream Top 40 airplay chart, it zips 20-15. With its Hot 100 jump, the pure-pop "Thing" passes the peaks of the first two R&B-flavored singles from Timberlake's album "The 20/20 Experience – 2 of 2": "Take Back the Night" reached No. 29 in September and "TKO" peaked at No. 36 in December.
"Thing" is Timberlake's 24th top 40 Hot 100 hit. He tallied another 10 with 'N Sync in 1998-2002.
-- Shakira, Rihanna: Rihanna grabs her 22nd No. 1 on Dance Club Songs, as Shakira's "Can't Remember to Forget You," featuring Rihanna, lifts 2-1. Dating to the chart's Aug. 28, 1976, inception as a national survey, Rihanna trails only Madonna, the leader with 43 No. 1s. "Forget" marks Shakira's sixth No. 1 and first since "Loca" in December 2010. She first reached the tally with the No. 3-peaking "Whenever, Wherever," her breakthrough English-language hit, in 2002.
"Forget" is the lead single from Shakira's self-titled album, released this week and due on next week's charts. The song dips 31-34 on the Hot 100, where it's reached No. 15.
-- Dierks Bentley: Bentley scores his first No. 1 in nearly two years, and his 11th overall, on Country Airplay, as "I Hold On" ascends 3-1. The Arizona native had most recently topped the chart with "5-1-5-0" (Aug. 4, 2012). He first reigned with his debut entry, "What Was I Thinkin'," in 2003. "Hold" steps 44-42 on the Hot 100.
-- Luke Bryan: He freshens up the top 10 on Hot Country Songs, as "Play It Again" flies 18-9, becoming his 15th top 10. It earns the chart's Digital Gainer nod with 48,000 downloads sold (up 52%), in the SoundScan tracking week ending on March 23. On Country Digital Songs, it sets a new peak, rising 6-3. "Play" adds Airplay Gainer applause, soaring 28-18 with 16 million audience impressions (up 82%) on Country Airplay. On the Hot 100, "Play" powers 81-53.
-- Calvin Harris: Harris claims the Hot 100's top debut at No. 69 and blasts 26-8 on Hot Dance/Electronic Songs with "Summer." His fourth top 10 on the latter chart (dating to its January 2013 launch; in that span, he and David Guetta share the lead for the most top 10s) enters Dance/Electronic Digital Songs at No. 5 with 45,000 downloads sold. The sum accounts for more than two-thirds of its Hot Dance/Electronic Songs points after the track debuted last week with an even split of early airplay and streaming.
-- Tim McGraw: As it lifts 25-21 on Hot Country Songs, Tim McGraw's "Lookin' for That Girl" arrives on the Hot 100 at No. 96. Dating to his first Hot 100 entry, "Indian Outlaw," 20 years ago this month (March 5, 1994), McGraw has debuted at least one title each year since. Should his latest reach the Hot Country Songs top 10, it will become his milestone 50th top 10 on the survey.
-- Enrique Iglesias: "El Perdedor," featuring Marco Antonio Solis, becomes Iglesias' record-extending 25th No. 1 on Latin Airplay (2-1), as well as Solis' 10th. Ricky Martin follows Iglesias with 13 leaders, with Gloria Estefan next with 11. Solis shares fourth place for the most Latin Airplay No. 1s with Wisin & Yandel.
-- Chino & Nacho: The Venezuelan duo scores its fifth Tropical Airplay No. 1, as "Chica Ideal" vaults 9-1 with Greatest Gainer honors (up 63 percent in plays). The pair has now tallied a No. 1 in each year dating its first No. 1, "Nina Bonita," in 2010.
-- HAIM: After denting the Alternative airplay chart for a week (No. 40, March 8), the sister trio's "Forever" roars 32-24 in its third week on Hot Rock Songs. Sales account for 66 percent of the track's chart points, as it debuts at No. 21 on Alternative Digital Songs (12,000, up 25 percent). Aiding its profile: its usage in Target's current TV ad campaign.
-- Beck: The alt rocker celebrates his first No. 1 on Triple A, as "Blue Moon" rises 3-1. Charting on the survey since 1998, he'd previously reached a No. 2 highpoint with "Think I'm in Love" in 2007.
