Two leading ladies, Mariah Carey and Madonna, leapfrog over Elvis Presley in the Billboard charts record book this week.

As expected, Mariah Carey moves past Elvis Presley and into sole possession of second place for most No. 1s in the rock era, as "Touch My Body" soars 15-1 on the Billboard Hot 100 to become her 18th chart-topper. With her album "E=MC2" yet to hit retail, Carey might equal the Beatles' record of 20 No. 1s before her set runs its course.

"Body's" blast to No. 1 is fueled by a record-setting debut week digital tally of 286,000 downloads. That sum, good enough for the No. 1 slot on Hot Digital Songs, surpasses the 277,000 downloads labelmate Rihanna opened with in the June 9, 2007, issue with her summer smash "Umbrella."

Presley will also be nudged from his standing as the artist with the most top 10s in the rock era, as Madonna surpasses him with her 37th top 10, "4 Minutes." The track, which features Justin Timberlake, clocks a 68-3 jump. Previous to the establishment of the Billboard Hot 100 in 1958, the industry standard chart was the Best Sellers in Stores tally, where Presley scored his first 12 top 10s.

Like Carey's "Touch," Madonna's Hot 100 jump is spurred by stupendous download sales. "4 Minutes" shifts 217,000 in its first week of wide release (it had been available as a Verizon exclusive) to enter Hot Digital Songs at No. 2.

This is the first time since Nielsen SoundScan began tracking digital sales in 2003 that two titles debut simultaneously on Hot Digital Songs with more than 200,000 downloads each. The week also marks the best single-week digital tally in either artist's career.
