Adele's '21' May Return to No. 1, In Time for Mother's Day

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:

10, Kelly Clarkson
4, Carrie Underwood
3, Jordin Sparks
2, Clay Aiken
2, (Chris) Daughtry
2, Ruben Studdard

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.

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."
