Weekly Chart Notes: Havana Brown, LMFAO, Dave Matthews Band

Australian singer/DJ Brown continues her U.S. breakthrough with 'We Run the Night,' while DMB returns with new single 'Mercy.'

Havana Brown continues her marathon rise up Billboard'sQ&A column, LMFAO's "Party Rock Anthem," featuring Lauren Bennett and GoonRock, manages a feat that only one other song in the Billboard Hot 100's 54-year history previously had.

As it rebounds 50-49 in its 68th week, "Party" becomes the second title to grace the Hot 100 a year after reaching No. 1. It began a six-week reign the week of July 16, 2011. (This week's charts are dated July 21, 2012.) The first such long-lasting topper? The Black Eyed Peas' "I Gotta Feeling," which rose to No. 1 on July 11, 2009, and remained charted through July 17, 2010.

"Party" additionally extends its record for the slowest fall from No. 1. Its 48-week decline is four weeks longer than the previous mark of 44 frames established by Savage Garden's "Truly, Madly, Deeply" in 1998.

"Party" is now one week from tying LeAnn Rimes' "How Do I Live" (69 weeks, 1997-98) for the second-longest stay in the Hot 100's archives. Jason Mraz's "I'm Yours" leads with a 76-week run in 2008-09.

'MERCY' MAKES ENTRANCE: Dave Matthews Band debuts its first song on the Triple A adult alternative chart since 2009, as "Mercy" launches at No. 12, marking the chart's highest launch by a group this year. The song previews the band's eighth studio album, "Away From the World," due Sept. 11.
