Idolator

In this week of financial horrors, created largely by formerly cocksure men, it’s perhaps apropos that a couple of ladies post the most gloat-worthy performances in the upper reaches of Billboard's Hot 100.

That starts at the top, where Pink, a nearly decade-long veteran of the chart wars, scores her first solo No. 1 (and second overall), “So What.” And she does it with the largest one-week digital sales total we’ve seen since the beginning of summer.

A few rungs down, U.K. chanteuse and Atlantic Records guinea pig Estelle stages a massive comeback. Her return to iTunes fuels a 44-space move by her Kanye West–supported single “American Boy,” to a new peak of No. 9. Not a moment too soon: one week before the official start of fall in the United States, and a month after it appeared to have peaked at No. 11, our runner-up in the Idolator 2008 Summer Jam competition is finally an official U.S. Top 10 hit. Revenge is sweet.

Last fall and winter, chart fans noted the return to the radio of a style that, until recently, was pretty unfashionable on Billboard's Hot 100: pure-pop female singer-songwriters.

Strummier and sunnier than their Lilith counterparts in the '90s and closer in kinship to California's post-Joni ladies of the '70s, two gals with hard-to-spell names led this '07 boomlet with a pair of Top Five smashes: Colbie Caillat, with "Bubbly," and Sara Bareilles, with "Love Song." The surprise success of American Idol's Brooke White, who seemed every week to be channeling Carole King, only fueled the theory.

Trouble is, neither Caillat nor Bareilles has had an easy time following up those easy-listening hits. Caillat has fared respectably, with a No. 20 followup ("Realize"), but not spectacularly. And Bareilles is completely stalled, with "Love Song" still leading the Adult Contemporary chart but no followup—on the Hot 100, or anywhere—all these months later.

So, new theory: maybe pop fans weren't latching onto these ladies' earthy-girl personas at all, but their sound.

Which brings us to Jason Mraz. He makes a big move into the Top 10 this week and, just in time for fall, proves the bedroom-girlypop sound can still hit big in 2008, even if the act in question possesses an extra Y chromosome.
