Take note, Dylan fans: It’s blond on blond at the top of the pop charts this week. The Dixie Chicks’ second major-label album, Fly, flew to the No. 1 slot its first week out, moving enough copies (341,000) to soar over Christina Aguilera’s self-titled debut (which slipped to No. 2 with 217,000 sold). Elsewhere, Carlos Santana’s surprise hit Supernatural got another shot of love from fans, cracking the top 5 for the first time. And the times they could be a-changin’ for Puff Daddy, whose Forever took a second-week tumble to No. 8, with just 119,000 sold. Is it all over now, daddy blue?
