American Idol champ Ruben Studdard and runner-up Clay Aiken may have fought a close race on the Fox talent show, but on the singles charts, it's no contest. Aiken's "Bridge Over Troubled Water" debuted at No. 1 with sales of 393,000 copies — far ahead of Studdard's "Flying Without Wings," which opened at No. 2 with 287,000 copies sold.
