HE'S THE GREATEST DANCER: Enrique Iglesias passes a King (of Pop) and a Prince for most No. 1s among solo males in the 34-year history of Dance/Club Play Songs.

"Tonight (I'm Lovin' You)," featuring Ludacris & DJ Frank E, rises 2-1 to become Iglesias' eighth leader on the list, besting Prince, who notched seven No. 1s between 1981 and 1991, and Michael Jackson (seven chart-toppers from 1983 to 1995, as well as an additional No. 1, "Lovely One"/"Can You Feel It"/"Walk Right Now," from "Triumph," as a member of the Jacksons in 1980).

"I am such a big fan of both Prince and Jackson, and to be included in this elite group of artists is such an honor," Iglesias tells Billboard.

"I've been reading Billboard since I was a child and I'm very proud to be part of music history."

Here is a recap of the singer's eight Dance/Club Play Songs No. 1s:

1999, "Bailamos"
2000, "Be With You"
2001, "Hero"
2002, "Escape"
2004, "Not in Love," featuring Kelis
2009, "Away," featuring Sean Garrett
2010, "I Like It," featuring Pitbull
2011, "Tonight (I'm Lovin' You)," featuring Ludacris & DJ Frank E

Among all artists in the chart's archives, Madonna leads with 40 No. 1s. Janet Jackson ranks second with 19 chart-topping titles, followed by Mariah Carey and Kristine W, each with 15.

LEGENDARY LEGACIES: Two iconic acts return to Country Songs with record-extending entries.

George Jones debuts at No. 59 as a guest on Staind frontman Aaron Lewis' "Country Boy," also featuring Charlie Daniels. With the song's launch, Jones becomes the only artist to appear on the list in each of the last seven decades. His 166 titles are the most in the chart's 67-year history.

Jones had last appeared on Country Songs in 2005 as a featured artist on Shooter Jennings' No. 26-peaking "4th of July." He made his format entrance with the No. 4 classic "Why Baby Why" the week of Oct. 29, 1955.

At No. 60, Alabama bows with "Are You Sure Hank Done It This Way?," marking the band's first visit since 2002 and 74th overall, the most among groups. Shooter Jennings' father Waylon's original recording of the ode to Hank Williams topped the Nov. 15, 1975, chart.

MARS OBSERVATIONS: Bruno Mars assumes the reins of two airplay charts with different songs.

"Grenade," which returns for a third week atop the Billboard Hot 100, rises 3-1 on Pop Songs, while "Just the Way You Are," his debut single as a lead artist, lifts 2-1 on Adult Contemporary. The latter track led Pop Songs for three weeks beginning Oct. 30, 2010.

Mars is just the second artist to dominate the Nielsen BDS-based airplay tallies simultaneously with different tracks since the Pop Songs list's inception in 1992. (The Adult Contemporary chart dates to 1961). Kelly Clarkson's "Since U Been Gone" spent seven weeks atop Pop Songs in 2005 while prior single "Breakaway" was amid a 21-week AC command.

After no solo males sent their first two chart entries as a lead artist to the Pop Songs summit in the chart's first 16 years, Mars is the third to accomplish the feat since 2009, following Jason Derulo and Taio Cruz.

Mars first ruled Pop Songs as a featured act on B.o.B's "Nothin' On You" the week of May 22, 2010.
