'N Sync, stop your smirking! As hinted here Tuesday, the Backstreet Boys's fourth album, Black & Blue, sold 1.6 million copies during its first week of release — far shy of the record 2.4 million units 'N Sync's No Strings Attached moved during its first week out in March. Still, Black & Blue easily took the No. 1 spot on the album chart and fared better than the group's last effort, Millennium, which sold 1.13 million copies in its debut week in 1999. Latin sensation Ricky Martin had a harder time looking on the bright side as his Sound Loaded slipped from No. 4 to No. 10 in its second week of release. Well, he could always go back to General Hospital.
