Dinah Jane Hansen, Normani Hamilton, Camila Cabello, Lauren Jauregui and Ally Brooke of "5th Harmony" attend Red Carpet Radio presented by Westwood One at Nokia Theatre L.A. Live on November 22, 2014 in Los Angeles, California.  

The group vaults 75-40 with its single co-written by Meghan Trainor. Meanwhile, Trainor and Taylor Swift chart four titles apiece.

As previously reported, Taylor Swift's "Blank Space" leads the Billboard Hot 100 for a seventh week, marking the record-tying 19th straight week that women have kept men out of the chart's top spot.

Who else soars on the Hot 100 this week? (Even some men do!)

James Newton Howard, "The Hanging Tree," featuring Jennifer Lawrence
After a two-week break, the collab, from The Hunger Games: Mockingjay, Part I, in which Lawrence stars, returns to the Hot 100's top 20 (21-16), nearing its No. 12 high set upon its debut four weeks ago. As 98 of the Hot 100's titles sport sales gains this week, thanks to online Christmas-week shopping, "Tree" grows by 106 percent to 170,000 sold in the week ending Dec. 28, according to Nielsen Music. On Radio Songs, it surges 36-29 with 38 million in all-format audience (up 13 percent).

Fifth Harmony, "Sledgehammer"
The quintet reaches the Hot 100's top 40 for the first time, as "Sledgehammer" rockets 75-40. Sales mark 73 percent of the track's activity, as it blasts onto Digital Songs at No. 28, up by 277 percent to 85,000 sold after it went on sale in the iTunes Store for 69 cents on Dec. 16. (It remains at that discount price.) In Fifth Harmony's prior two Hot 100 visits, debut hit "Miss Movin' On" reached No. 76 and "Bo$$" rose to No. 43. "Sledgehammer" - co-written by Meghan Trainor - could experience further gains on next week's charts following the group's performance on Pitbull's New Year's Revolution, broadcast Dec. 31/Jan. 1 on Fox. Speaking of Trainor …

Meghan Trainor
As smash singles "Lips Are Movin" and "All About That Bass" ranks at Nos. 4 and 5 on the Hot 100, respectively, "Dear Future Husband" re-enters at a new high of No. 64 and "Title" bows at No. 100. The songs sold 57,000 (up 205 percent) and 32,000 (up 197 percent), respectively. All four tracks appear on Trainor's debut full-length Title, due Jan. 13.

Taylor Swift
Like Trainor, two album cuts join two monster singles ("Space" and "Shake It Off," the latter at No. 9 on the Hot 100), all from Billboard 200 leader 1989. "Bad Blood" returns at No. 78 (a new peak) and likely next single "Style" re-enters at No. 84. They sold 60,000 (up 268 percent) and 50,000 (up 66 percent), respectively, in the tracking week.

Prince Royce, "Stuck on a Feeling," featuring Snoop Dogg
The Latin superstar makes his bid for crossover success, as the track debuts on the Hot 100 at No. 93. Airplay contributes the majority of its points, as it gains by 10 percent to 22 million in audience. It also lifts by 72 percent to 15,000 sold.
