Fred Bronson reports on the latest the latest chart activities of Jennifer Lopez, the Atco label and No. 1s on Billboard's Mainstream Top 40 list.

'RIGHT' THING TO DO: Jennifer Lopez returns to Billboard's Hot 100 with her highest-debuting song in two years. "Get Right" (Epic) is a new entry at No. 53, the highest opening position for a Lopez single since "All I Have," her collaboration with LL Cool J, bowed at No. 25 in December 2002.

"Get Right" is the third-highest debut of Lopez' career, behind "Waiting for Tonight," which started at No. 56 in October 1999. This new song is the 13th chart entry for Lopez on the Hot 100. The actress' first song to appear on the Hot 100 was "If You Had My Love," which debuted at No. 81 the week of May 15, 1999, and went on to rule the survey for five weeks.

On Billboard's Hot R&B/Hip-Hop Singles & Tracks chart, "Get Right" is a new entry at No. 62. That's the second-highest debut for Lopez on this list. "I'm Real," her highest debuting title, opened one notch higher at No. 61 in June 2001.

WHERE IT'S ATCO: Bobby Darin's biggest hits, including his signature recording of "Mack the Knife," were released on Atlantic Records' subsidiary label, Atco. The label was briefly reactivated in the late 1980s, but after a few years was retired again.

The imprint is back on The Billboard 200 this week, as the soundtrack to the Bobby Darin biopic starring Kevin Spacey earns Hot Shot Debut honors at No. 141. "Beyond the Sea" (Atco/Rhino) is the first Atco album to chart since August 2001, when Buffalo Springfield's "Box Set" debuted and peaked at No. 194. "Beyond the Sea" is the highest-charting release on Atco since July 1990, when "Funk-O-Metal Carpet Ride" by Electric Boys went to No. 90.

Darin's first Atco LP to appear on the Billboard album chart was "That's All," which peaked at No. 7 in 1960. He had eight Atco chart albums in all, with the final one being "Things & Other Things," No. 45 in 1962.

'OVER' AND OUT: "Over And Over" (Curb/Derrty) by Nelly featuring Tim McGraw ends its No. 1 reign on Billboard's Mainstream Top 40 chart after 11 weeks, putting the track in a four-way tie for the second longest running No. 1 in the history of the survey.

"Over" shares the honor with "Torn" by Natalie Imbruglia (1998), "One Sweet Day" by Mariah Carey and Boyz II Men (1996) and "I Love You Always and Forever" (1996) by Donna Lewis. Only "The Sign" by Ace Of Base, with 14 weeks on top in 1994, has lasted longer at No. 1.
