The Recording Industry Association of America (RIAA) has certified OutKast's two-disc "Speakerboxxx/The Love Below" triple-platinum for U.S. shipments of 3 million copies.

The Recording Industry Association of America (RIAA) has certified OutKast's two-disc "Speakerboxxx/The Love Below" triple-platinum for U.S. shipments of 3 million copies. The feat was accomplished just one month after Arista released the Atlanta-based duo's fifth studio album on Sept. 23. The album has been No. 1 three of the six weeks that it has been on The Billboard 200.

According to its criteria, the RIAA counts each unit within a multi-disc set towards its total, therefore 1.5 million shipped copies of the title are counted as 3 million for certification purposes.

"Speakerboxxx/The Love Below" is Big Boi and Andre 3000's fourth consecutive multi-platinum title. Released in 2000, the single-disc "Stankonia" is also a triple-platinum, while 1988's "Aquemeini" and 1996's "ATLiens" are each certified for 2 million copies shipped.

Faith Hill's 1998 Warner Bros. release "Faith" reached the six times platinum level in October, while Pink's 2001 Arista set "M!ssundaztood" and Hank Williams Jr.'s 1982 Curb "Greatest Hits" set hit the five times platinum mark. Jennifer Lopez's 2000 collection "J. Lo" (Epic) was certified for 4 million copies shipped and Evanescence's Wind-Up debut, "Fallen," for 3 million.

Reaching the double-platinum mark was 3 Doors Down's "Away From the Sun" (Universal) and the Columbia soundtrack to the film musical "Chicago."

The solo debut from Dave Matthews and Hilary Duff's first non-holiday album each notched platinum honors in October. The former's RCA set "Some Devil" and the latter's "Metamorphosis" (Walt Disney Records) were each certified by the RIAA for U.S. shipments of 1 million copies. Also reaching the platinum plateau were John Mayer's "Heavier Things" (Columbia), Nickelback's "The Long Road" (Roadrunner) and Mary J. Blige's "Love & Life" (Geffen).
