The first single by Australian duo Madison Avenue, "Don't Call Me Baby," grabs the #1 spot on Billboard's Hot Dance Music/Club Play chart this week, ending the two-week reign of Rosabel's "Don't You Want My Love" in the top slot.

"Don't Call Me Baby" (RealAudio excerpt) is the debut collaboration of Melbourne producers Andy Van and Cheyne Coates, who are veterans of Australia's dance-music community. The track, which held the #2 spot last week, has been on the chart for eight weeks, and is "a big hit, especially among women," according to Serebe Kironde, a manager at New York's Eightball Records. "The girls are always requesting that song from the DJs; they love it."

A remix of the song by the hot production trio the Dronez — Erick Morillo, Jose Nunez and Harry "Choo-Choo" Romero — is included on the single (RealAudio excerpt of remix). Madison Avenue's debut LP is due this fall.

Basement Jaxx's "Bingo Bango" edges up a notch to #2, while "Don't You Want My Love," a remake of a 1978 disco hit by Debbie Jacobs-Rock, who also sings on the new version (a collaboration between house producers Ralphi Rosario and Abel Aguilera), slips to #3.

Kironde noted that in light of the enduring Latin-music trend, Basement Jaxx's catchy, Latin-influenced beats on "Bingo Bango" (RealAudio excerpt) may have helped propel it up the chart. Remixes by David Morales and Chicago "ghetto funk" producer DJ Funk are also included on the vinyl-only double 12-inch.

Ariel's "Woman in Love" edges up one to #4, and "Filthy Mind" by Amanda Ghost rounds out the top five.

In the chart's biggest gain, Deborah Cox's "I Never Knew" leapfrogs to #11 from #22 last week, in just its third week on the chart. The song was originally written and produced by Rodney Jerkins for the Toronto-born singer's 1998 sophomore album, One Wish. The current single is remixed by Hani. Cox is in the studio working on her third album, while her collaboration with Whitney Houston, "Same Script, Different Cast," appears on Houston's recently released greatest-hits package.

"['I Never Knew'] is danceable, the lyrics are good, and it's just dope," said Kironde, who added that Eightball sold roughly 60 copies of the single on Thursday alone.

Meanwhile, Chicane's "Don't Give Up" (RealAudio excerpt), which features vocals by veteran pop singer Bryan Adams, drops out of the top five to #6 this week. Mariah Carey's "Can't Take That Away (Mariah's Theme)" enters the top 10 at #7, up from #12 last week. The single features a remix by David Morales.

Moving up to #8 after dropping two spots last week is Olive's "I'm Not in Love" (RealAudio excerpt), while Ann Nesby's "Love Is What We Need," falls to #9.

Finishing out the top 10 is David Morales and Albert Cabrerra's "Higher," which jumps from #15 to #10.
