Rated R: Remixed (stylized as Rated R /// Remixed) is the second remix album by Barbadian singer Rihanna. It was released on May 8, 2010, in Brazil and Europe and on May 24, 2010, in the United States by Def Jam Recordings. It contains remixes from her fourth studio album, Rated R (2009). The songs were solely remixed by Chew Fu. The majority of the remixes were remastered to incorporate influences from the genre of house music, and incorporate heavy usage of synthesizers as part of their instrumentation.
Rated R: Remixed received a mixed review from Jean Goon for MSN Entertainment. She praised Fu for remixing some of the dark and sombre songs into upbeat dance songs, but criticized the album as it did not provide memorability. The album peaked at number four in Greece and number six on the US Dance/Electronic Albums chart; it peaked at number 33 on the US Top R&B/Hip-Hop Albums chart and number 158 on the US Billboard 200 chart. As of July 2010, Rated R: Remixed has sold 13,000 copies in the US, according to Nielsen SoundScan.
