WEEK IN PREVIEW: DIXIE DOES IT AGAIN

The Chicks’ success with Home (Open Wide/Columbia) speaks volumes about the public’s continuing taste for roots music, given that its largely stripped-down bluegrass sound has moved over a million in its first two weeks and the upcoming chart should reflect another 200k or so in sales for the week just completed.

Of course, those numbers also speak volumes about the Chicks themselves, who have captivated their expanding audience to such an extent that they could probably release a polka album without skipping a beat. Or an oom-pa-pa, for that matter.

This week, the new Disturbed album has people who know about such things talking new #1. Conventional wisdom has it that Believe (Warner Bros.) will move about 300k, making it a pretty safe bet that it’ll top next week’s chart.

In radio, our Top 40 analysts with the highest security clearance say the most adds for the week will go to either Pink or John Mayer, with Cam’ron and Subarbabes close behind. Kelly Rowland and American Idol’s Kelly Clarkson, meanwhile will clean up after last week’s frenzy.

In Crossover, look for the Missy Elliott reports to fly, though "Work It" (GoldMind/Elektra) has already charted, with Mario, Dub C and Justin Timberlake close behind. And in Post Modern, it’s all about Saliva, whose "Always" (Island/IDJ) should score the most adds easily, while Jack Johnson, the already heavily played Red Hot Chili Peppers and Queens of the Stone Age should see heavy action as well.
