She had previously led for seven frames with "Umbrella," featuring Jay-Z, in 2007 and as a guest on Eminem's "Love the Way You Lie" last year.
"Found" equals Adele's "Rolling in the Deep" - the year's No. 1 Hot 100 song  - for the chart's longest rule this year. The lastsong to lead the list longer? Ke$ha's "TiK ToK," which began clocking a nine-week domination in January 2010.
"Found" extends its stay in the Hot 100's penthouse by spending a fourth week at No. 1 on Hot 100 Airplay with 146 million all-format audience impressions (up 2%), according to Nielsen BDS. On the Hot Digital Songs chart, the track holds at No. 2 for a third frame, after five frames at No. 1, with 149,000 downloads sold (down 9%), according to Nielsen SoundScan.
Below Rihanna's Hot 100 leader, LMFAO's "Sexy and I Know It" logs a sixth week at No. 2. The cut rebounds 3-1 on Hot Digital Songs, although with a 5% decrease to 149,000 downloads sold, while holding at No. 2 on Hot 100 Airplay (110 million, down 1%).

Bruno Mars' "It Will Rain" remains at No. 3 on the Hot 100 for a third week, claiming Greatest Gainer/Airplay honors for a second consecutive week as it surges 8-4 on Hot 100 Airplay (96 million, up21%). On Hot Digital Songs, "Rain" falls 1-4 (129,000, down 22%).

"One" rises with gains in both airplay and sales, logging identical 7-6 upticks on Hot 100 Airplay and Hot Digital Songs. On the former chart, the song swells to 92 million in audience (up 12%), while on the latter list, it increases by 24% to 117,000 downloads sold.
As previously reported , the sales momentum of "One" is owed in part to its 69-cent sale pricing in the iTunes Store. (This week's chart is the first to reflect its sales activity since its digital discount took effect). As of this posting, the song remains the only title among the iTunes Store's top 75 songs available for less than $1.29.

The Fox TV troupe's exposure of the song - marking one of the few times that the show has remade a song not yet a current mass-appeal hit; itpreviously covered Bruno Mars' album cut "Marry You" - concurrently spurs Fun.'s original, featuring Janelle Monae, to debut on the Hot 100 at No. 53, logging digital sales of 49,000 (up from 3,000) and a 34-28 advance on the Alternative radio airplay chart.
