It was released by Island Records on April 4, 2005, and in North America on April 12, 2005 (see 2005 in music). The album focuses on several R&B-related genres, ranging from 1970s retro soul to quiet storm, gospel, and others. It received generally positive reviews and won a Grammy Award in 2006 for "Best Contemporary R&B Album". After debuting at number one with Carey's highest first-week sales during that time, it became the biggest selling album of 2005 in the U.S., according to Nielsen SoundScan. The Emancipation of Mimi has been certified six times platinum by the RIAA, and it is Carey's best-selling album in the U.S. since Daydream (1995). In August 2006, Def Jam reported that the album had sold more than 10 million copies worldwide.
