American Idol champ Ruben Studdard and runner-up Clay Aiken are going head-to-head again — this time on the album charts. RCA plans to release both of their upcoming as-yet-untitled albums on the same day, Aug. 19, Billboard.com reports. If single sales are any indication, Aiken will likely come out on top; his "Bridge Over Troubled Water" trumped Studdard's "Flying Without Wings" 393,000 copies to 287,000 copies.
