Weekly Chart Notes: Elton John, Taylor Swift, Shakira

'BACK' AT ONE: Darius Rucker notches his fourth No. 1 on Country Songs, as "Come Back Song," the cleverly titled first single from his second country album, "Charleston, SC 1966," advances 2-1.

With the set having topped Country Albums last week, Rucker is the first male artist since Country Songs and Country Albums converted to Nielsen data in 1990 and 1991, respectively, to rule the surveys with his first two charted albums and the first radio single from each album. The first two chart entries ("Don't Think I Don't Think About It," "It Won't Be Like This for Long") from his 2008 No. 1 debut country collection, "Learn to Live," reached No. 1 on Country Songs.

Over the past two decades, only Carrie Underwood has also managed the feat, reigning with each of her first three albums and the maiden radio singles from each set.

'SALE' FORTH: Shakira takes over the top of six charts with the arrival of her new album "Sale El Sol" and first single "Loca."

The set is Shakira's fifth No. 1 on Latin Albums and Latin Pop Albums. It marks her fifth top 10 on the Billboard 200 (No. 7), and first since "Oral Fixation Vol. 2" opened at No. 5 the week of Dec. 17, 2005.

"Loca," featuring El Cata, becomes Shakira's ninth No. 1 on Latin Songs with an 11-1 blast. Among women, only Gloria Estefan has more (14). The song becomes Shakira's 13th Latin Pop Songs leader (4-1), second among all acts only to Enrique Iglesias' 16, and reaches the Latin Digital Songs and Tropical Songs summits.

Credited to Shakira featuring El Cata or Dizzee Rascal, "Loca" logs the greatest positional gain (84-32) on the Hot 100.

Donna Summer celebrates her 14th No. 1 on Dance/Club Play Songs, as "To Paris With Love" rises 3-1.

The renowned diva's chart-topping sum equals Beyonce's and trails only those of Madonna (40), Janet Jackson (19), Mariah Carey and Kristine W (15 each), dating to the chart's inception as a national ranking Aug. 28, 1976. Summer extends her record for longest span of Dance/Club Play Songs No. 1s, having scored her first topper, "Four Seasons of Love (all cuts)," 34 years ago next week.

"I wanted to give my fans something special and exciting and I couldn't think of a better theme than the glamour and allure of Paris," says Summer of her newest hit. "I want people to feel transported, whether they're listening on the dance floors of Ibiza or on their headphones at work.

"The idea is to let them escape into that magic world."

Steve Carrell, John Stewart and Stephen Colbert debut at No. 4 on Comedy Digital Songs with "Everybody's Talking 'Bout Sully."

The song, which premiered on Comedy Central's autism benefit "Night of Too Many Stars" (Oct. 21), lauds pilot Chesley Sullenberger, who safely landed US Airways Flight 149 in the Hudson River off New York City in January 2009.

Non-chart-related highlight from the special: an uncomfortable Larry David acting frustrated that Sullenberger would not vacate a more desirable aisle seat while fielding telephone pledges.

(At least, hopefully, it was an act).
