American Idol winner Kelly Clarkson saw her new double-A-side record ‘A Moment Like This’/’Before Your Love’ rose from the No 52 spot to No 1 after going on sale in stores last week, marking the biggest leap to No 1 in the history of the Hot 100, her label, RCA Records, said on Wednesday. “We’re in uncharted territory” said Geoff Mayfield of Billboard magazine, which publishes the charts. “It’s unusual to have a retail single to begin with, and it’s even more unusual to have one sell decent numbers.”

The album sold 236,000 copies its first week in stores, the first time since 1999 that a single has sold more than 200,000 copies.
