As previously reported, OMI's "Cheerleader" is No. 1 on the Billboard Hot 100 (dated Aug. 15) for a fourth week, while The Weeknd closes the gap at No. 2 with "Can't Feel My Face."

Who else makes notable moves on the Hot 100 this week?

Demi Lovato, "Cool for the Summer"
The song reaches the Hot 100's top 20 (24-19) in its fifth week with across-the-board gains following the July 23 arrival of its official video. It zooms 18-12 on the Digital Songs chart with 63,000 downloads sold (up 17 percent) in the week ending July 30, according to Nielsen Music; 31-18 on Streaming Songs (6.6 million U.S. streams, up 49 percent); and, 22-18 on Radio Songs (56 million audience impressions, up 9 percent). (It'll be interesting to see if the song, which is so summer-themed in its lyrics, can continue its momentum past Labor Day.)

Charlie Puth, "Marvin Gaye," featuring Meghan Trainor
Puth lands his second top 40 Hot 100 hit, following the 12-week No. 1 "See You Again," on which he assists Wiz Khalifa (now at No. 5), and Trainor her fourth, as their name-checking tribute to the soul legend jumps 48-36, led by its 27-18 jump on Digital Songs (52,000, up 25 percent). It also gains by 19 percent to 21 million in radio audience and by 38 percent to 3.2 million domestic streams.

While Gaye last hit the Hot 100's top 40 as a lead with the No. 3-peaking "Sexual Healing" in 1983, a year before his passing (before returning posthumously as a featured act on Erick Sermon's No. 22 hit "Music" in 2001), his name has now appeared in three top 40 hits in the last four years. Prior to Puth and Trainor's track, Drake's "Marvins Room" rose to No. 21 and Big Sean's "Marvin & Chardonnay," featuring Kanye West and Roscoe Dash, reached No. 32, both in 2011.

Meanwhile, Trainor surges with her other collab currently on the Hot 100: "Like I'm Gonna Lose You," featuring John Legend, lifts 77-68.

5 Seconds of Summer, "She's Kinda Hot"
The song tumbles to No. 54 on the Hot 100 from its No. 22 debut, thanks to its 3-35 plummet on Digital Songs (32,000, down 74 percent), a not-atypical second-week decline for high-profile releases. Still, the song is off to a strong start at radio, roaring 24-19 on Pop Songs (up 31 percent in plays), suggesting a future rebound on the Hot 100.

Janet Jackson, "No Sleeep," featuring J. Cole
Jackson's single re-enters the Hot 100 at a new high, No. 63, after it spent one prior week on the chart last month, at No. 67. (And, now that's he's featured on the song, Cole is added in the artist field.) The July 24 premiere of its official video spurs the track's return to the chart, as it enters Streaming Songs at No. 50, up by 647 percent to 3.2 million U.S. streams. The sleek single also holds at its No. 4 high on the Adult R&B Songs airplay chart.

Bea Miller, "Fire N Gold"
The 16-year-old pop singer, who placed ninth on the second season (2012) of Fox's since-canceled The X Factor, makes her first Hot 100 appearance, as "Fire N Gold" enters as the Hot Shot Debut at No. 78. Sales is its greatest driver, as her debut full-length album, Not an Apology, charges in at No. 7 on the Billboard 200 (33,000 units). Miller made prior inroads with previous single "Young Blood," which reached No. 40 on Pop Songs in December.
