From Radio and Records:

Also notable is the return of Madonna, who clocks in at No. 23 on CHR/Top 40 with “4 Minutes” (Warner Bros.), her record-tying 26th chart hit (and first in two years). The preview single from “Hard Candy,” due April 29, matches the format mark for most charted titles set by Mariah Carey just five weeks ago with “Touch My Body” (IDJMG). “4 Minutes,” featuring Justin Timberlake, who inducted Madonna into the Rock and Roll Hall of Fame earlier this month, also takes Most Increased Plays (up 2,147, the format’s best gain in more than three years) and is the list’s highest arrival since Christina Aguilera’s "Ain’t No Other Man" roared in at No. 21 in June 2006.
