Her career has seen its share of ups and downs, but pop princess Britney Spears is definitely back on top as she headlines this week's 411 Playlist.

Billboard.com reports that Spears' ' "I Wanna Go" has her dancing all the way to the record books. Her single gives her the distinct honor of being the artist with the longest span of number one hits on Billboard's Mainstream Top 40 chart. Britney's reign started twelve years ago with "Baby One More Time."

The pop diva's 'B In The Mix: The Remixes Vol. 2' is set for release on October 11th.

On to a man who is no stranger to breaking records himself, the late Michael Jackson is to be honored in Wales with "Michael Forever: The Tribute Concert." The star-studded event includes everyone from host Jamie Foxx to Christina Aquilera and Smokey Robinson.

According to the Los Angeles Times, the singer's manslaughter trial is expected to begin in the last week of September. Jackson's former doctor is accused of supplying the King of Pop with a lethal dose of surgical anesthetics.

Whitney Houston has been subject to tabloid fodder for alleged drug-use herself, but the diva may be making a comeback. The singer's publicist confirms that the singer is in talks to return to the silver screen in the remake of "Sparkle." Houston made a name for herself as an actress after her role in the 1992 hit, "The Bodyguard."

And while Houston looks to make a bigscreen comeback, heavy metal is working its way back into the mainstream. September 14th was no ordinary day in New York City because heavy metal rockers, Anthrax, Matallica, Slayer and Megadeath (aka the Big Four) invaded Yankee Stadium. Before the big show, Anthrax sad down with Fox 411 and talked about their first album in eight years, "Worship Music." The band dubbed the new material as a "true heavy metal album." Drummer and guitarist Charlie Benante added that with the return of Joey Belladonna the record sounds like "classic Anthrax."

"Worship Music" is currently available.
