Nelly Furtado remains the queen of summer 2006 in America after scoring a fourth week on top of the Billboard pop charts. The Canadian singer/songwriter's catchy hip-hop anthem “Promiscuous” has kept Gnarls Barkley's megahit “Crazy” off the top of the charts for a second week. That tune stands firm at number two.

Cassie's “Me & U” and Shakira's “Hips Don't Lie” complete the top four. John Mayer scores the week's highest debut - his “Waiting On The World To Change” enters the Hot 100 chart at number 25.

In other U.S. chart news, Koji Kondo's “Super Mario Brothers Theme” tops the Hot Ringtones list, while Daniel Powter's “Bad Day” nets a 13th week atop the Adult Contemporary countdown.

Meanwhile, the Red Hot Chili Peppers' 13-week reign at number one on the Mainstream Rock chart has come to an end - the group's “Dani California” hit has been toppled by Three Day Grace's “Animal I Have Become.”

In more bad news for the Red Hot Chili Peppers, they've also given up the number-one spot on the Billboard Modern Rock chart to The Raconteurs' “Steady, As She Goes.”
