Shania Twain's 'Come on Over' hits 20 million in US

Her 1997 album "Come on Over" has been certified 20 times platinum by the Recording Industry Association of America (RIAA), the music industry trade group that oversees the awards.

"Come on Over" is the best-selling country album in history, according to the RIAA. Only five artists have titles that have shipped more copies to U.S. retailers: the Eagles (1976's "Their Greatest Hits 1971-1975," 28 million); Michael Jackson (1982's "Thriller," 26 million); Pink Floyd (1979's two-disc "The Wall," 23 million); Led Zeppelin (1971's "Led Zeppelin IV," 22 million); and Billy Joel (1985's two-disc "Greatest Hits, Vol. I & II," 21 million).

(For its accounting purposes, the RIAA counts each disc of a multiple-disc release as a single unit toward a title's total.)

Twain's entry into that pantheon debuted at No. 1 on Billboard's Top Country Albums and No. 2 on the Billboard 200 chart upon its release. Eleven of the 16 tracks reached Billboard's Hot Country Singles & Tracks chart, including the No. 1 hits "You're Still the One," "Love Gets Me Every Time" and "Honey I'm Home."

Other recent RIAA platinum certifications included Evanescence's "Fallen" (6 million), Josh Groban's "Closer" (4 million), John Mayer's "Room for Squares (4 million), George Strait's "50 #1s" (3 million), Ray Charles' "Genius Loves Company" (2 million) and Nelly's simultaneously released "Suit" and "Sweat" albums, honored for shipments of 2 million and 1 million, respectively.
