'21' SALUTE: As Adele 's "21" tops the Billboard 200 for a 17th week , the set moves closer to the mark for most weeks at No. 1 for an album by a woman. In the 56-year history of the survey, only the Whitney Houston -led soundtrack to "The Bodyguard" has reigned longer among solo females (20 weeks, 1992-93).
Thus, the magic number of weeks at the summit that "21" will need to become the longest-leading album by a female artist? 21.
(The album continues its reign on the Billboard 200 by holding off the set that debuts directly below it at No. 2: "Kidz Bop Kids 21").
Billboard.com reader prumjabi88 commented that 21 is already a lucky number for Adele. "Set Fire to the Rain" becomes the third Billboard Hot 100 No. 1 from "21"  in its 21st week on the chart (rising 2-1).
Adele sure has come a long way since her first Hot 100 entry, "Chasing Pavements." The week of Feb. 28, 2009, the song peaked at No. 21.
On the Official U.K. Albums chart this week, Adele equals Queen and Oasis' marks for most total weeks at No. 1: 21. She's led for 20 weeks with "21" and one with predecessor set "19" in 2008.
Or, since the start of the 21st century.
(Or, considering the set's dominance, the "21" century).
EVER-'LAST'-ING: One of Adele's biggest influences? Etta James .
Upon the release of "21" last year, Adele told NPR  that the R&B/soul legend, who passed away Friday (Jan. 20) at 73, shaped her affinity for blues that readily infuses the set.
"I saw the most stunning woman I've ever seen in my life," Adele recalled of first finding a James hits compilation album. "She had this beehive weave, and these catty eyes, and this seductive figure, and this look on her face, like, 'Don't mess with me.'
"She went right through me," Adele said of the "At Last" crooner. "It was the first time that I'd ever been so moved by someone's voice. It was like she was singing (material directly to) me, about me, 50 years after she recorded it."
Adele mused that she can't picture enjoying the adulation and longevity that marked James' career.
"I'd love to," she said, "but it's pretty unlikely."
'FIRE' AND REIGN: The Hot 100 coronation of "Set Fire to the Rain" marks the eighth song with "fire" in its title to top the tally and the fifth No. 1 with "rain" in its name.
The eight "fire" leaders that clearly put the "hot" in Hot 100:
Title, Artist, Date Reached No. 1 (Weeks at No. 1)
"Light My Fire," the Doors, July 29, 1967 (three)
"Fire," Ohio Players, Feb. 8, 1975 (one)
"Chariots of Fire - Titles," Vangelis, May 8, 1982 (one)
"St. Elmo's Fire (Man in Motion)," John Parr, Sept. 7, 1985 (two)
"We Didn't Start the Fire," Billy Joel, Dec. 9, 1989 (two)
"Fireflies," Owl City, Nov. 7, 2009 (two)
"Firework," Katy Perry, Dec. 18, 2010 (four)
"Set Fire to the Rain," Adele, Feb. 4, 2012 (one to-date)
... and the five "rain" songs that have reigned:
"Raindrops Keep Fallin' on My Head," B.J. Thomas, Jan. 3, 1970 (four)
"Laughter in the Rain," Neil Sedaka, Feb. 1, 1975 (one)
"I Love a Rainy Night," Eddie Rabbitt, Feb. 28, 1981 (two)
"Blame It on the Rain," Milli Vanilli, Nov. 25, 1989 (two)
"Set Fire to the Rain," Adele, Feb. 4, 2012 (one to-date)
(A song just shy of both lists: James Taylor's "Fire and Rain." The ballad peaked at No. 3 in 1970).
Parr's update of "St. Elmo's Fire" - "Tim Tebow's Fire" - has sold 1,000 downloads in its two weeks of release, according to Nielsen SoundScan. After the New England Patriots' 45-10 rout of the Denver Broncos (Jan. 14) ended the quarterback's well-documented season , the song slumped by 73% in sales this week.
PERFECT 10: Following the return of "American Idol" on Fox Jan. 18, the series' original queen Kelly Clarkson  celebrates her 10th Hot 100 top 10, as "Stronger (What Doesn't Kill You)" powers 21-8.
Here is an updated look at the show's graduates with multiple Hot 100 top 10s:
TWO KINDS OF 'LOVE': Fox's other musical juggernaut likewise impacts the Hot 100 following its return last week (Jan. 17).
With five debuts, the "Glee" cast  extends its record count to 184 career Hot 100 hits. As its remakes of Rihanna 's "We Found Love," featuring Calvin Harris (No. 56), Maroon 5 's "Moves Like Jagger," featuring Christina Aguilera  (No. 62), and Roberta Flack's "The First Time Ever I Saw Your Face" (No. 70) debut, the ensemble has returned 55 former Hot 100 No. 1s to the tally.
An interpretation of "Love" by a troupe even younger than the McKinley High singers enters the Kid Digital Songs chart: Kidz Bop Kids' version opens at No. 9.
GLORI(A)OUS: As "Hotel Nacional" follows "Wepa" to the top of Dance/Club Play Songs, Gloria Estefan  scores her seventh No. 1 on the survey.
The ascent marks her first consecutive leaders since her first three No. 1s - "Tradicion," "Turn the Beat Around" and "Everlasting Love" - topped the chart in succession in 1993-95.
In between, Estefan led with "Tres Deseos (Three Wishes)" (1996) and "Oye" (1998).
'OVER'-ACHIEVER: Gavin DeGraw  posts his first No. 1 on Adult Pop Songs, as "Not Over You" rises 2-1. He had previously peaked in the top 10 with "I Don't Want to Be" (No. 9, 2004); "Chariot" (No. 5, 2005); and, "In Love With a Girl" (No. 5, 2008). On Pop Songs, "Over" advances 11-10, marking his third top 10.
The coronation of "Over" also grants co-writer Ryan Tedder his fifth Adult Pop Songs No. 1 as a writer. Two compositions by his band OneRepublic  have hit the top - Timbaland's "Apologize," featuring the group, in 2008 and last year's "Good Life" - as have Leona Lewis' "Bleeding Love" (2008) and Kelly Clarkson's "Already Gone" (2009).
MOVING 'UP': Radio is figuring out what fans already knew about Jason Mraz 's optimistic love song "I Won't Give Up."
The lead single from Mraz's as-yet-untitled fourth studio album, due May 8, debuted atop Digital Songs two weeks ago and its to-date sales stand at 396,000, according to SoundScan. Now being promoted to adult pop and adult alternative radio, the ballad begins on Adult Pop Songs at No. 36.
"Since its inception, I've referred to this collection of songs as 'the Love album,' " Mraz says  of the new set. "Love is and will always be multi-faceted. It's comedy in the face of tragedy. It's romance on the deck of a sinking ship. It's where the sacred meets the silly.
"It's having compassion for your enemies and being nice to the dining room table after you've stubbed your toe. It's what turns you inside out and makes you go nuts, like having a song stuck in your head for months, but you know it's not a song at all.
"It's your life."
