"I can't believe it's been over 10 years since my first album and it was really exciting to put all of my favorite songs in one collection for my fans," said Aguilera in a statement.
Aguilera is following a growing list of acts who have struck exclusive deals with retailers. Wal-Mart has had huge success with similar deals with The Eagles, Journey, and Garth Brooks; AC/DC's October release of "Black Ice" will be available only at Wal-Mart, its affiliated Sam's Club and the band's Web site. The Eagles comeback album, "Long Road Out of Eden," was the third-best selling CD of 2007 with 2.6 million copies sold.
Target exclusively released John Legend's "Live from Philadelphia" in January and has had other exclusive releases of special edition albums by the likes of Alicia Keys and Carrie Underwood.
