Never underestimate the power of a woman with a banjo.That's the lesson to be learned from next week's "Billboard" album chart, where country dolls the Dixie Chicks will debut at number one according to sales figures released by SoundScan on Wednesday. The Chicks sold more than 341,000 copies of their latest effort, "Fly," to land atop the chart after one week in stores. The Chicks bumped teen pop sensation Christina Aguilera out of the top spot after the "Genie in a Bottle" singer spent just one week at number one with her self-titled debut album. Megadeth post the next highest debut of the week landing at number 16 with "Risk," which sold more than 74,000 copies in its first week out. Other notable debuts include the "Blue Streak" soundtrack at 33, the Beatnuts' "Musical Massacre" at 35, Days of the New's self-titled effort at 40, Staind's "Dysfunction" at 132, Vitamin C's self-titled at 172, and Rammstein's "Live Aus Berlin" at 180.
