Mark Ronson, Bruno Mars Lead Hot 100; Sam Smith, Fetty Wap Hit Top 10

Mark Ronson's "Uptown Funk!," featuring Bruno Mars, rules the Billboard Hot 100 for an 11th week, while Sam Smith's "Lay Me Down" and Fetty Wap's "Trap Queen" each  jump into the top 10.

As we do each Wednesday, let's cover all the "up" and "down" action in the top 10 on the sales/airplay/streaming-based Hot 100.

"Funk!," released on RCA Records, becomes just the 19th No. 1 in Hot 100 history to lead for at least 11 weeks. It's just the second to reach that level this decade: Robin Thicke's "Blurred Lines," featuring T.I. and Pharrell, began a 12-week command in June 2013.

The Longest-Leading Hot 100 No. 1s

"Funk" logs an 11th week atop the Digital Songs chart with 189,000 downloads sold (down 10 percent) in the week ending March 15, according to Nielsen Music.  It's now one of just three songs to lead Digital Songs for at least 11 weeks: Flo Rida's "Low," featuring T-Pain, racked a record 13 weeks on top in 2007-08, while Pharrell Williams' "Happy" dominated for 11 weeks last year.

"Funk" leads the subscription services-based On-Demand Songs chart (4.9 million U.S. streams, down 4 percent) for a 10th week and Streaming Songs (16.9 million, down 3 percent) for a ninth. On Radio Songs, "Funk" reigns for an eighth week with 178 million in all-format audience (down 2 percent).

Ronson and Mars' collab, thus, leads the Hot 100 and its three main component charts (Digital Songs, Radio Songs and Streaming Songs) simultaneously for a record-extending seventh week (nonconsecutively).

Maroon 5's "Sugar" hits a new high on the Hot 100, rising 3-2. It holds at No. 2 on Digital Songs (178,000, up 4 percent) and No. 4 on both Radio Songs (123 million, up 7 percent) and Streaming Songs (9.9 million, up 4 percent). With its advance, "Sugar" becomes the highest-peaking Hot 100 hit from Maroon 5's album V. Lead single "Maps" reached No. 6 and follow-up "Animals" rose to No. 3.

With Maroon 5's climb to No. 2 on the Hot 100, Ed Sheeran's "Thinking Out Loud" falls to No. 3 after peaking at No. 2 for eight weeks. "Loud" keeps at No. 2 on Radio Songs (146 million, down 5 percent) and Streaming Songs (10.9 million, down 7 percent) and slips 3-5 on Digital Songs (137,000, down 13 percent).

Ellie Goulding's "Love Me Like You Do" holds at No. 4 on the Hot 100 after hitting No. 3 three weeks ago. The Fifty Shades of Grey soundtrack single stays at No. 3 on Streaming Songs (10.6 million, up 2 percent) and No. 4 on Digital Songs (152,000, down 2 percent). "Love" adds the Hot 100's top Airplay Gainer award for a second week, lifting 7-6 on Radio Songs (97 million, up 25 percent).

Rihanna, Kanye West and Paul McCartney's "FourFiveSeconds" is stationary at No. 5 on the Hot 100 after rising as high as No. 4 three weeks ago. The superstars' single also spends a sixth week at No. 1 on Billboard's Hot R&B/Hip-Hop Songs chart; The Weeknd's "Earned It (Fifty Shades of Grey)" rises to a new Hot 100 high (7-6); and Taylor Swift's "Style" dips from its No. 6 Hot 100 peak to No. 7. As previously reported, "Style" becomes Swift's fifth No. 1, and the third from her album 1989, on the Pop Songs airplay chart.

Sam Smith blasts 58-8 on the Hot 100 with "Lay Me Down." The ballad claims top Digital and Streaming Gainer honors as it soars onto Digital Songs at No. 3 with a 472 percent increase to 157,000 downloads sold, thanks in large part to John Legend's inclusion on a newly-released remix. The track also re-enters Streaming Songs at No. 9 (6.2 million, up 157 percent), while approaching Radio Songs with 19 million in audience (up 5 percent).

Smith and Legend teamed up on the song, and in a new video for it, in support of Red Nose Day, a biennial event in which British residents and celebrities wear clown noses to raise funds and awareness for those in need in the UK and throughout the world.

"Down" is the third Hot 100 top 10 from Smith's album In the Lonely Hour. Lead single "Stay With Me" reached No. 2 and "I'm Not the Only One" followed with a No. 5 peak. The set is the first by a solo male to generate three Hot 100 top 10s since Eminem's The Marshall Mathers LP 2 yielded "Berzerk" (No. 3), "Rap God" (No. 7) and "The Monster," featuring Rihanna (No. 1, four weeks), in 2013-14.

"Down" is Smith's fourth Hot 100 top 10 overall: Disclosure's "Latch," on which he's featured, became his first, reaching No. 7 last August. Smith and Ariana Grande are the only acts with as many as four top 10s since then.

Pitbull and Ne-Yo's "Time of Our Lives" stays at its No. 9 Hot 100 peak, while rapper Fetty Wap hits the top 10 on his first try with "Trap Queen" (12-10). The track gains by 17 percent to 9.6 million streams and holds at No. 6 on Streaming Songs. On Digital Songs, it bounds 17-12 (68,000, up 15 percent). "Queen" also nears Radio Songs with an 18 percent gain to 22 million.

The New Jersey-born Fetty Wap (real name: Willie Maxwell) lost the use of his left eye as a child. "When I was little, I got into a little accident and it gave me congenital glaucoma in both of my eyes," he recently explained. But, "the doctors saved one, so I was blessed to [still] have my vision."

As for female royalty in chart hits, "Trap Queen" is just the fifth top 10 hit in Hot 100 history with the word "queen" in its title. The others: Bobby Darin's "Queen of the Hop" (No. 9, 1958); ABBA's "Dancing Queen" (No. 1, one week, 1977); Juice Newton's "Queen of Hearts" (No. 2, 1981); and Billy Ocean's "Caribbean Queen (No More Love on the Run)" (No. 1, two weeks, 1984).

(Honorable mentions to two regal rock bands: Queen logged four top 10s, including two No. 1s, in 1978-92 and Queensryche tallied one, the No. 9 ethereal classic "Silent Lucidity," in 1991.)
