GOING WITH THE FLO: It's been the top song on the Billboard Hot 100 for six weeks, but Flo Rida's "Right Round" makes new headlines this week by rising 2-1 on the Mainstream Top 40 radio airplay chart.

The song is the Sunshine State rapper's second No. 1 on the airplay list. His debut entry "Low" was honored as Billboard's top Hot 100, Pop 100, Mainstream Top 40, Rhythmic and Digital song of 2008.

With the coronation of "Right Round," Flo Rida gains entrance to the elite club of rappers to collect multiple No. 1s in the Mainstream Top 40 chart's 16-year archives. Here is a look at the rap artists who have made repeat visits to the summit, with featured billings noted:

Total No. 1s, Artist, Titles
4, Nelly, "Hot in Herre," "Dilemma," "Shake Ya Tailfeather,"' "Over and Over"
2, Eminem, "Without Me," "Lose Yourself"
2, Flo Rida, "Low," "Right Round"
2, Ja Rule, "I'm Real," "Ain't It Funny" (Jennifer Lopez featuring Ja Rule)
2, Kanye West, "Gold Digger," "Stronger"
2, T.I., "My Love" (Justin Timberlake featuring T.I.), "Live Your Life"


ALL 'TOLD': UNDERWOOD, TRAVIS BACK IN TOP 10:
Randy Travis becomes the first artist in 27 years to send a title into the top 10 twice on Hot Country Songs, as Carrie Underwood's cover of his 1988 chart-topper, "I Told You So," on which he's featured, rises 11-9.

Until Travis this week, no artist had taken the same composition into the top 10 in updated form since Dolly Parton reigned with her original "I Will Always Love You" in 1974 and a re-recording in 1982 (a third take, with Vince Gill, climbed to No. 15 in 1995).

The collaboration, Travis' 30th top 10 and his first since the No. 1 "Three Wooden Crosses" in 2003, marks the first top 10 cover of a prior top 10 by any artist since Blake Shelton rose to No. 10 in June 2005 with a remake of Conway Twitty's 1988 No. 7 ballad "Goodbye Time."

Underwood's album "Carnival Ride," which includes the original solo recording of "Told," the version that country radio first played before the rendition featuring Travis was serviced, now boasts its fifth top 10 on Hot Country Songs. The first four - "So Small," "All-American Girl," "Last Name" and "Just a Dream" - all reached the summit.

A CHART FIT FOR THE KINGS: Kings of Leon follow their first Modern Rock No. 1, "Sex on Fire," by sending "Use Somebody" 2-1. The act is the first at the format to score back-to-back leaders since RCA labelmates Foo Fighters scored a third consecutive No. 1 with "Let It Die" in August.

Kings of Leon, who prior to "Sex on Fire" had charted on the airplay tally only with the No. 23-peaking "The Bucket" in 2005, become the first act to link consecutive No. 1s without having logged a previous top 10 since Alanis Morissette arrived with "You Oughta Know" and "Hand in My Pocket" in 1995.

GIRL POWER: Francesca Battistelli vaults 4-1 on Hot Christian AC Songs with "Free to Be Me" to become the first female artist to top the radio chart since Nichole Nordeman reigned with "Brave" in summer 2005. Battistelli is only the fourth solo female to lead the list since its July 2003 launch. The singer/songwriter joins Nordeman, Christy Nockels (2004) and Joy Williams (2005).

COMPLETE BEAT: Check back tomorrow for this week's expanded Chart Beat encompassing all of our charts. We'll see if Lady GaGa’s "Poker Face" makes Flo Rida read 'em and weep by dislodging the latter from the Billboard Hot 100 summit. On the Billboard 200, the tight battle for the top spot is expected to be won by either the soundtrack to "Hannah Montana: The Movie" or the "Now 30" hits compilation. New albums from Keri Hilson and Papa Roach are also due in the chart's upper reaches.
