Critics gave mixed reviews to the album. Some reviewers called B in the Mix: The Remixes a good remix compilation, while others argued that the album was conceived as a product and also criticized what they perceived as weak vocals. B in the Mix: The Remixes charted in countries such as Belgium, Japan, Italy and the United States, where it peaked at number four on the Billboard's Dance/Electronic Albums. As of November 2007, the album had sold 1 million copies worldwide, making it the ninth best selling remix album of all time. It received minimal promotion by Spears' standards. "And Then We Kiss" was released as the only single from the album in Australia and New Zealand.
On September 28, 2005, Jive Records announced through a press release that Spears would release a remix album titled Remixed. However, on November 8, 2005, it was reported by Jennifer Vineyard of MTV that the album was actually titled B in the Mix: The Remixes, and was going to be released on November 22, 2005. The album includes songs from her previous albums remixed by DJs such as Peter Rauhofer and Stuart Price. Price had previously remixed "Breathe on Me" from In The Zone for a limited edition bonus disc of Spears' 2004 compilation, Greatest Hits: My Prerogative. B in the Mix: The Remixes also includes one new song, "And Then We Kiss"; the song had previously been set to be included on a bonus disc of her 2005 DVD Britney & Kevin: Chaotic, but was left out for unknown reasons.B in the Mix: The Remixes had two covers. In the American edition, Spears does not appear on the cover; there is a butterfly instead. Vineyard noted this saying, "[the album] is being marketed in a more underground way than usually associated with a superstar act". In the international edition, Spears appears behind the butterfly.
