Who else surges on the Hot 100 this week?

Natalie La Rose, "Somebody," featuring Jeremih
As La Rose's debut hit, partly based on Whitney Houston's 1987 Hot 100 No. 1 "I Wanna Dance With Somebody (Who Loves Me)," rises 15-13 on the chart, it grants the Amsterdam-born singer a notable honor: The song becomes her first Billboard No. 1, topping the Rhythmic Songs airplay chart. La Rose is just the third woman in the last 10 years to crown Rhythmic Songs with an introductory entry (as a lead), following Tinashe ("2 On," 2014) and Cassie ("Me & U," 2006).

Ariana Grande, "One Last Time"
On the Hot 100, the track rises 18-16. Meanwhile, with its 11-10 lift on Pop Songs, Grande tallies a fifth top 10 on the airplay chart from her album My Everything. The set's lead single, "Problem" (featuring Iggy Azalea), became her first Pop Songs No. 1.

Meghan Trainor, "Dear Future Husband"
Trainor zooms back to the Hot 100 with "Dear Future Husband," the third single from her debut Billboard 200 No. 1 album Title. The track re-enters at a new high of No. 47. Lead smash "All About That Bass" topped the Hot 100 for eight weeks and follow-up "Lips Are Movin" reached No. 4.

Kendrick Lamar Earns His First No. 1 Album on Billboard 200 Chart

As Lamar's To Pimp a Butterfly rockets onto the Billboard 200 at No. 1, six songs from the set enter the Hot 100, including this track at No. 91, which brings funk innovator Clinton back to the chart. ("Uptown Funk!" surely exists in part because of sounds that Clinton pioneered decades ago.) He'd made one prior solo appearance: Ice Cube's "Bop Nation," featuring Clinton, reached No. 23 in 1994. With Funkadelic/Parliament/Parliament-Funkadelic, he charted 14 Hot 100 hits in 1969-96, rising as high as No. 15 with 1976's "Tear the Roof Off the Sucker (Give Up the Funk)." He'd last charted under the Parliament-Funkadelic billing as featured on Too Short's "Gettin' It."
