There's barely even a retail market for singles anymore, with Billboard's Hot 100 singles chart determined largely by airplay. At least, that was true until this week, when Kelly Clarkson's double-A-sided single ''Before Your Love''/''A Moment Like This'' hit stores and promptly sold 236,000 copies, according to SoundScan. The ''American Idol'' winner registered what Billboard called the biggest jump in the history of the chart, rocketing from No. 52 to No. 1 in one week. ''We're in uncharted territory,'' Billboard chart director Geoff Mayfield said Wednesday, noting that Clarkson's was the first single to sell more than 200,000 copies since 1999.
In fact, it sold more than every album this week save one. That was Disturbed's ''Believe,'' which debuted at No. 1 on the album chart on sales of 283,625. The hard rockers ended the three-week chart reign of the Dixie Chicks' ''Home'', pushing it to second place with 168,350 copies sold. Avril Lavigne's ''Let Go'' was also pushed down one place to third, selling 131,975 units. Nelly's ''Nellyville'' held at No. 4 and sold 125,300 discs, while Eminem's ''The Eminem Show'' slipped two spots to No. 5 and moved 116,975 copies.
Ludacris' side project Disturbing tha Peace scored a No. 6 debut with ''Golden Grain,'' followed by a No. 7 debut for Lifehouse's ''Stanley Climbfall.'' Norah Jones' ''Come Away With Me'' slid one space to No. 8. Kenny G's ''Paradise,'' at No. 9, was the week's fourth top 10 debut. Falling five notches to No. 10 was Toby Keith's ''Unleashed.''
