CLARKSON COMMANDS COUNTRY: The original "American Idol" queen concurrently celebrates her first trip to No. 1 on Country Songs.

"Don't You Wanna Stay" becomes Jason Aldean's fifth Country Songs leader and the first for duet partner Kelly Clarkson, who joins Carrie Underwood (11) and Josh Gracin (one) as the only "Idol" graduates to reach No. 1 on the survey.

Clarkson had made two previous Country Songs visits. "A Moment Like This" peaked at No. 58 in 2002 and Reba McEntire's remake of Clarkson's "Because of You" with the maiden "Idol" victor rose to No. 2 in 2007.

Chart Beat reader John Maverick of Burt County, Neb., points out that "Don't" is the chart's first pop/country No. 1 duet since Bon Jovi and Sugarland's Jennifer Nettles reigned with "Who Says You Can't Go Home" for two weeks in May 2006.

(That's not including Kenny Chesney's 2008 No. 1 "Everybody Wants to Go to Heaven" with the Wailers, widely considered a core reggae act).

Only two other duets between pop and country artists have ruled Country Songs in the past quarter-century.

Chesney and Uncle Kracker's "When the Sun Goes Down" led for five weeks in 2004 and Alan Jackson and Jimmy Buffett's "It's Five O'Clock Somewhere" crowned the chart for eight frames in 2003.

Unlike Clarkson, however, Uncle Kracker and Buffett (Billboard's Nashville correspondent in 1969-70) have each charted as sole lead acts on Country Songs top 10s.

Uncle Kracker climbed to No. 6 with "Smile" last September and Buffett peaked at No. 8 with "Hey Good Lookin'" (with guests Chesney, Jackson, Clint Black, Toby Keith and George Strait) in 2004.

"Don't" marks the first Country Songs No. 1 duet featuring a solo artist never billed as a top 10 title's only lead act since Julio Iglesias joined Willie Nelson on the two-week No. 1 "To All the Girls I've Loved Before" in 1984.

While Nelson has charted 122 titles on the survey, the song remains Iglesias' lone Country Songs chart entry.

LOVING 'WORDS': Despite falling shy of this season's top 24, former "Idol" contestant Chris Medina makes a swift arrival on the Hot 100's Bubbling Under chart and Heatseekers Songs, where "What Are Words" debuts at Nos. 14 and 22, respectively.

Proceeds of the song's sales contribute to a fund established for Medina's brain-damaged fiancee, Juliana.

After notifying Medina of the judges' decision not to advance him in the competition on the series' Feb. 23 episode, an emotional Lopez was comforted by Tyler and fellow judge Randy Jackson.

Now, Lopez can take consolation that she and Medina share a Billboard chart honor: both have reached rankings with songs written by accomplished writer/producer Rodney Jerkins.

Jerkins penned Lopez's five-week Hot 100 No. 1 "If You Had My Love" and Medina's debut chart entry.

"I always knew who (he) was, but after doing some research, I didn't realize how 'the man' he actually was," said Medina of learning that Jerkins wanted to collaborate.

"The words totally embody what my situation is. It's heartfelt, it's real and it was an honor to be asked to put my voice to this wonderful material."
