Week of June 13

For the second time in a month, the No. 1 song on my charts is a song that has also topped Billboard's Hot 100. But unlike "Break Your Heart," the Taio Cruz-Ludacris collaboration that went to No. 1 in Billboard several weeks before topping my charts, "California Gurls" by Katy Perry featuring Snoop Dogg ascends to Billboard's No. 1 this week, a week after topping my charts.

By staying atop my charts this week, "California Gurls" stops the revolving door that has gone on since mid-March, when V.V. Brown's "Shark in the Water" spent two consecutive weeks at No. 1. In that streak, 10 songs spent a week at the top (including a nonconsecutive one-week return for "Shark"). On the subject of nonconsecutive No. 1 runs, it's possible that The Bird and the Bee's "Heard It on the Radio" could join that club. This week, it rebounds 5-3.

Some significant drops from the Top 10 and in the lower part of the chart as well, provide momentum for several hits, including Nikki Yanofsky's "Cool My Heels" (21-10), Erik Hassle's "Hurtful" (35-28) and "Stop for a Minute" from Keane featuring K'naan (28-21).

Just two debuts this week. "King of Anything" at No. 36 is Sara Bareilles' fifth Top 40 hit, following three solo releases and her No. 2 collaboration with OneRepublic, "Come Home." And Hanson returns to the Top 40 for the first time in three and a half years, with "Waiting for This" at No. 37. Last time out, they took "Great Divide" to No. 21 in 2006-07.
