Country stars Carrie Underwood and Blake Shelton make notable moves this week on Billboard's Christian music rankings.

American Idol 2005 champ Underwood returned to help close out the Fox series' 15-season run April 7 with an emotional performance of her 2014 hit "Something in the Water." In the tracking week following the appearance (ending April 14), the song gained by 108 percent to 12,000 sold, according to Nielsen Music, and vaults 5-1 on Christian Digital Songs. The ballad spends its 23rd week at No. 1 on the list, and first since March 28, 2015; it debuted at No. 1 on Oct. 18, 2014, and has sold 1.1 million to date.

"Something," which Underwood co-wrote, logged 26 weeks atop Hot Christian Songs in 2014-15. Only Hillsong United's "Oceans (Where Feet May Fail)" has spent more time at No. 1: 61 weeks.

Also on Hot Christian Songs, another core country artist, Shelton, makes his first appearance. Shelton's hymn-like "Savior's Shadow," from his album If I'm Honest (May 20), bows at No. 17. Selling 7,000 in its opening week, it arrives on Christian Digital Songs at No. 4 (and Country Digital Songs at No. 43).

ON THE MOVE: 7eventh Time Down strides into the Hot Christian Songs top 10 with "God Is On the Move" (13-10), the rock band's second top 10, following 2013's No. 9-peaking "Just Say Jesus."

LEADING OFF: Todd Dulaney achieves his first No. 1 on Gospel Airplay with "The Anthem" (2-1). The singer-songwriter was a minor league baseball player in the New York Mets farm system in 2003-04 but retired in 2005 to take a swing at musical hits instead.
